Terms of Service

01 · Who you're agreeing with

These Terms of Service (the Terms) are an agreement between you and the individual sole trader trading as “GymVim” who is named, with a postal address, in the Impressum (GymVim, “we”, “us”). They cover the GymVim apps for iPhone and Android, the smartwatch companion, this website, and the servers behind them. We'll call all of that the Service.

There's no company here. GymVim is made and run by one person, and “we” is only used because it reads better than a name repeated four hundred times. In practice that means support and legal correspondence go through a single human being, so give it a reasonable amount of time. It also means §13 is worth reading before you rely on the app for anything important.

Download it, install it, make an account, or just open it as a guest, and you're agreeing to what's on this page. If any of it doesn't sit right with you, don't use the Service.

Our Privacy Policy covers what happens to your personal data and is part of this agreement. Where the two ever disagree on a data question, the Privacy Policy wins.

02 · Who can use GymVim

You need to be at least 16, or older if your country sets a higher age for agreeing to online services. Under 18? Then you're confirming a parent or guardian has read this and is fine with it.

You can't use the Service if the law or a sanctions regime says you can't, or if we've previously closed your account for breaking these Terms.

Signing up on behalf of an organisation? Then you're confirming you're allowed to commit them, and “you” means them as well as you.

03 · Your account

You sign in with a one-time code emailed to you, or with Google or Apple. GymVim has no password of its own, which is good news for a lot of reasons, but it does mean your account is only as secure as your email inbox or your Google or Apple account.

So, a few things we're asking of you:

• Use an email address that works, and keep it current, so we can actually reach you about your account.
• Keep sign-in codes to yourself. We will never ask you for one. Not by email, not in chat, not on the phone. Anyone who does is trying to steal your account.
• Keep a lock on your phone, and don't hand your account to other people.
• Tell us at [email protected] quickly if something looks wrong.

What happens under your account is your responsibility, unless the cause was something on our side. To make that fair, Profile → Profile Settings → Devices & Sessions lists every active login with its device, rough location and last-used time, and lets you end any of them, or every other one at once, on the spot.

One person, one account. Spinning up extra accounts to dodge a restriction or to get an edge in a group breaks these Terms.

04 · What you get

GymVim tracks training. Depending on the version you're running, that means following or building programs, logging workouts set by set, browsing the exercise library, charting measurements and progress photos, pulling readings from Apple Health or Health Connect, running your session on a paired watch and, on Apple Watch, saving the finished workout into your Apple Health, showing a live heart rate while you train and keeping each workout's average and peak, setting goals, joining groups with shared goals and leaderboards, and turning a workout into a share image, a share link or a dare for someone else to take on.

All of it is free today. There are no tiers, no subscriptions, no in-app purchases and no ads. Whatever the app can do, it does for everyone who has it, and nothing is locked behind a payment. That is how things stand now rather than a promise for all time; §12 has the detail.

Features get added, changed and sometimes removed as the app develops (§13), so please don't build your life around any single one being there forever.

Most of it needs an internet connection. Sets you log while offline are held on your phone and sent when you're back online, but if you uninstall the app or clear its data before that happens, they're gone, and there's nothing we can do about it.

05 · Your body, your call

GymVim is not medical advice. It's not a medical device either. Nothing in it, whether that's a plan, a suggested weight, a calorie number, a body-fat figure or an exercise instruction, is a diagnosis, a treatment, or professional guidance from a doctor, physio, dietitian or qualified trainer. It's written by a software developer, not a medical or fitness professional, and none of it has been medically reviewed or certified by anyone.

Talk to a healthcare professional before you start or change a training programme. That goes double if you're pregnant, coming back from injury or surgery, dealing with a heart, joint, metabolic or respiratory condition, taking medication that affects how your body handles exertion, or you've been out of training for a long time.

You train at your own risk. Lifting things carries a real chance of getting hurt. Choosing the exercise, the weight, the intensity and the form is on you, as is the state of your equipment and the space around you, as is stopping when something hurts. Pre-filled weights and reps are a convenience built from what you or your plan recorded last time. They're a starting suggestion, not an instruction, and they have no idea how you slept or what your shoulder is doing today.

Calorie figures, volume totals, personal-record detection, comparisons with real-world objects and chart trends are all estimates worked out from whatever data the app has. They can be wrong, and they're not something to make a medical or dietary decision on. Readings imported from Apple Health or Health Connect are taken as those systems report them; we don't check them.

The heart-rate readout is not a heart monitor. If you train with a paired watch, GymVim can show your current pulse while you work out. That number is your watch's, passed through and displayed as it arrives: we don't verify it, we don't store it, and we don't act on it. The average and peak kept with each workout are your watch's figures too, saved as it reports them and not checked or corrected by us. Nothing in GymVim watches your heart rate, and nothing will warn you about a reading that's too high, too low, or irregular. There is no alarm, no threshold and no monitoring of any kind, and the reading can lag, drop out or be plain wrong depending on your watch, its fit and its sensor. It's there to look at between sets, nothing more. Never use it to decide whether you're safe to keep training, and if you have any reason to be concerned about your heart, use a device meant for that and speak to a doctor.

The Apple Health entry is a record, not a verdict. Finish a workout on the Apple Watch app and, if you've allowed it, the watch saves it into your Apple Health as a strength-training workout, with the duration and the heart rate and energy your watch measured. Those figures are your watch's, written as it reports them, and we don't verify or correct them. The entry lives in your own health store: managing or deleting it is done in the Health app, and once it's there it's governed by Apple's terms and privacy policy rather than ours. Refuse the Health permission and nothing is written; discard a workout and nothing is written either. What the app does with health data, in both directions, is set out in the Privacy Policy.

Timers, cues, rest alarms and notifications are conveniences that depend on your operating system, and phones delay or swallow them all the time. Don't lean on them anywhere a missed alert could hurt someone.

06 · House rules

Use GymVim for what it's for, stay on the right side of the law, and don't make life worse for anyone else. Concretely, don't:

• Harass or abuse people. No threats, hate speech, sexual harassment, bullying or stalking, and nothing that demeans someone over race, ethnicity, nationality, religion, disability, sex, gender identity, sexual orientation, age or body type.
• Upload illegal or harmful material. That includes sexual content, anything sexual involving minors in any form whatsoever, graphic violence, material promoting self-harm or eating disorders, promotion of illegal substances including banned performance-enhancing drugs, and anything that tramples someone's copyright, trademark, privacy or personality rights.
• Post pictures of other people without their say-so, and never a photo of anyone under 18 as a progress photo, group cover, avatar or share image.
• Pretend to be someone you're not, or pick a name, avatar or group title that's deceptive, offensive, or implies you're connected to GymVim when you aren't.
• Mess with the Service. No probing, scanning or penetration testing without written permission, no flooding it with traffic, no working around rate limits, authentication, quotas or access controls, and obviously no malware.
• Scrape it or abuse the API. No bots, crawlers or scripted clients beyond the official apps. No bulk-pulling the exercise library or anything else. No republishing our content as your own or as a rival dataset.
• Reverse engineer the apps, except where mandatory law expressly allows it, meaning § 69e UrhG and Art. 6 of Directive 2009/24/EC, and only that far.
• Resell or sublicense the Service, or use it as raw material for a competing product.
• Dodge enforcement, for example by making a new account after a suspension.

Content that breaks these rules gets removed, and §17 covers what else might follow. If you run into something ugly, report it to [email protected].

07 · Leaderboards and dares: don't cheat

Groups exist so a few people can push each other toward something, and a dare is a challenge between two people. A leaderboard or a dare result is worth exactly nothing if the numbers on it are invented. So on top of §6, don't:

• Log workouts you didn't do, or pad the weight, reps, distance or duration to climb or hold a position, or to beat a dare's time.
• Automate or fake the logging. No scripts, no macros, no modified clients, no hand-crafted API calls posting results that never happened.
• Run multiple accounts, or team up with other people to skew a group's standings.
• Farm a bug that produces impossible numbers. Tell us instead, at [email protected].
• Mess with membership, whether that's mass-inviting strangers or joining a group purely to wreck it.

Where there's good reason to think results were faked, we may correct or delete the entries or a dare result, reset a leaderboard, remove you from a group, or cut off access to the feature. For something serious or repeated, the account goes (§17). You'll be told what happened and why, and you can argue your case by replying.

One more thing worth knowing before you join anything: the other members can see your display name, avatar, rank and contribution to the shared goal. Don't join a group with people you wouldn't want seeing that. §7 of the Privacy Policy spells out exactly what's visible and what isn't.

08 · Your stuff stays yours

You own what you make. Workouts, programs, custom exercises, notes, measurements, progress photos, group covers, share images: all of it (Your Content) is yours, and we're not claiming otherwise.

For the app to work, though, we need permission to actually handle it. So you give us a limited, worldwide, non-exclusive, royalty-free licence to host, store, back up, copy, transmit, adapt (resizing an image, converting a file) and display Your Content, purely to run, secure and support the Service for you, and to show it to other people where you've chosen to make it visible. That licence lasts as long as the content is in the Service and ends when you delete it or your account, apart from copies sitting in backups until they rotate out.

What we don't do with it: advertising, selling it, or feeding your training data, measurements or photos into anything that trains a model. None of that, ever.

The flip side is that Your Content is your responsibility. You're confirming you have the rights to it, that it doesn't step on anyone else's, and that it follows §6. We're not obliged to police it, but we can review and remove anything we've got good reason to think breaks these Terms or the law.

Send us feedback, an idea, a bug report, a feature you wish existed, and we can use it freely, without owing you anything for it. Feedback isn't confidential, so don't send us a secret.

09 · Share links and dares are public

Make a share link for a program or a custom exercise, share a workout, send a dare, send a group invite, or turn on Post as a page for a card, and you've made a public web page. Anyone holding that link can open it without an account, and links get forwarded. Treat one as public the moment it exists. When you share a link, the image you're sharing becomes its preview in chat apps too.

By creating a link you're letting whoever receives it view the item and, where the app offers it, import a copy into their own library or take the workout on. A workout link or a dare shows the workout and its time but never the weights you lifted, and your first name only if you chose to show it; the Privacy Policy (§7) lists exactly what's on each page.

Dares. A dare stays open for 30 days. Whoever takes it does the same workout with their own weights, and their time is compared with yours. Their result reaches you only if they agree to send it, and yours reaches them on the same terms. A rematch is a new dare. A dare is a friendly challenge, not a competition with a prize: nothing is won or owed, and we don't referee it beyond the rules in §7.

Revoke a link, dare or page under Profile → Profile Settings → Sharing and it stops working, but copies already imported, results already sent, and things people already saw or saved, aren't coming back.

Don't share content you don't have the rights to, and don't use share links, dares or pages to spread anything §6 rules out.

10 · Our stuff stays ours

The Service, meaning the apps, the code, the backend, the interface, the design, the illustrations, the anatomy diagrams, the animations, the icons, the exercise library with its descriptions and media, the GymVim name and logo, and the intellectual property in all of it, belongs to us or to the people who licensed it to us, and copyright and trademark law protect it.

As long as you're sticking to these Terms, you have a personal, limited, revocable, non-exclusive, non-transferable and non-sublicensable licence to install and use the apps on devices you own or control, for your own private, non-commercial training. That's the whole of it. Nothing is granted by implication, and anything not spelled out here stays with us.

So: no copying, modifying, distributing, selling, leasing, publicly displaying or building derivative works from the Service or its content. Don't strip out proprietary notices, and don't use the name, logo or brand assets without asking first.

Think something in the app infringes your rights? Write to [email protected] with enough detail to find the material and understand the claim, and it'll be looked into properly.

11 · Other people's services

GymVim leans on things we don't control: the App Store and Google Play, Google and Apple sign-in, Firebase, Apple Health and Health Connect, your watch, Instagram if you share a story there, and your phone's notification and share systems. Those run under their own terms and privacy policies, and when they change something, we find out roughly when you do.

The Apple part

Apple requires the following for the iPhone app, and it overrides anything above that contradicts it:

• This agreement is between you and GymVim only, not with Apple. Apple isn't responsible for the app or anything in it.
• Apple has no obligation to provide any maintenance or support for the app.
• If the app fails to match any applicable warranty, you can tell Apple, and Apple will refund the purchase price, if there was one. To the maximum extent the law allows, Apple has no other warranty obligation of any kind.
• Apple isn't responsible for handling any claim you or anyone else makes about the app, covering product liability, regulatory compliance and consumer protection, and isn't responsible for investigating or defending a third-party intellectual property claim about it either.
• You're confirming you're not in a country under a US Government embargo or designated as “terrorist supporting”, and that you're not on any US Government list of prohibited or restricted parties.
• You have to comply with any applicable third-party terms when you use the app. Your mobile data plan is the usual example: if using GymVim over cellular puts you over your allowance, that's between you and your carrier.
• Apple and its subsidiaries are third-party beneficiaries of these Terms and can enforce them against you directly.

If you have a question or a complaint about the app itself, bring it to us rather than to Apple, at the addresses in §21.

On Android, the Google Play Terms of Service apply alongside these.

12 · What it costs (nothing, for now)

GymVim is free today. There are no paid tiers, no subscriptions, no in-app purchases, no free trials that turn into something, and no ads. Every feature the app has is available to everyone who installs it.

That means there's no payment method to give us and no card details for us to lose, because we do not ask for them today and have no mechanism to charge you. There's nothing to cancel, nothing to restore, and no billing that could outlive your account. If anything anywhere asks you to pay for GymVim itself, it isn't us.

The referral program isn't running either. The only thing it handed out was paid access, and there isn't any.

Charging for something later isn't ruled out. If that ever happens it's a material change: these Terms and the Privacy Policy get updated first, you get notice under §18, and any payment would go through the Apple App Store or Google Play with you agreeing to it there. You will never be charged for GymVim without that.

13 · Downtime and changes

We work to keep the Service up and behaving, but nobody can promise it never breaks. Maintenance, updates, infrastructure trouble, network outages and things well outside our control all interrupt it sooner or later. Where planned maintenance is likely to be noticeable, we'll say so in the app if there's time.

Features get added, changed and removed, and in principle the whole Service could be shut down. If that happens, or if a change would seriously spoil how you use the app, you'll get reasonable notice, at least 30 days where that's realistic, and a window to export your data (§15 of the Privacy Policy explains how).

Here's the honest part: one person maintains this. Support, fixes and updates depend on that person being available. Illness, other commitments, or life in general can slow a reply or an update down, and in the worst case can make carrying on impossible. If that day comes you'll get as much warning as the circumstances allow, and the data export will stay working for as long as it can.

You'll need a supported device, a current-ish OS and an internet connection. Support for older platforms ends occasionally, with notice. Anything labelled beta, preview or experimental may be unstable, may change without warning, and may vanish.

14 · What we don't promise

To the fullest extent the law allows, the Service comes “as is” and “as available”, with no warranties of any kind, whether express, implied or statutory. That includes implied warranties of merchantability, fitness for a particular purpose, title and non-infringement, and anything that might otherwise be read in from how the industry usually behaves.

In plainer terms: we're not promising the app will get you to your goals, that it'll always be up, that it'll never lose a set, or that any number, estimate, plan or chart is accurate or right for you.

If you're a consumer, none of that touches your statutory rights. Mandatory German consumer law, and the mandatory consumer law of your own country if you're elsewhere in the EU, applies regardless of what this section says.

15 · Who pays if it goes wrong

Some liability can't be limited, and we're not going to pretend otherwise. We're fully liable, without any cap, for harm to life, body or health; for anything caused intentionally or through gross negligence; for claims under the German Product Liability Act (Produkthaftungsgesetz); and for anything else the law refuses to let us exclude, including mandatory consumer law where you live, and personal injury in any jurisdiction where excluding it would be void anyway.

For ordinary carelessness, meaning slight negligence, we're liable only where we've broken a material contractual obligation. That means a duty which makes performing this agreement possible at all, and which you're entitled to rely on. Even then, liability is limited to the foreseeable damage typical for an agreement like this one.

Beyond that, and as far as the law permits, we're not liable for indirect, incidental, special, consequential or punitive damages, for lost profits, for lost training data or content, for damage to reputation, or for what it costs you to use something else instead, even if we knew it was a possibility.

Where liability is limited rather than excluded, everything you could claim across a twelve-month period tops out at EUR 100. GymVim is free today, so there are no fees to measure that against instead.

And we're not liable for what happens if you ignore §5, whether that's training past what your body can handle, brushing off medical advice, or treating an estimate as though a professional had said it.

These limits also protect anyone we bring in to help perform this agreement (vicarious agents under § 278 BGB), and they survive after the agreement ends.

16 · If you land us in trouble

If you use the Service in a way that breaks these Terms or the law, and somebody comes after us because of it, you'll cover the damage, reasonable legal costs included, but only as far as it's genuinely your doing. This doesn't cut into any mandatory consumer rights, and it doesn't apply where the problem was on our side.

17 · Leaving, and being asked to leave

Your side. Stop whenever you like, and delete the account under Profile → Profile Settings → Data & Account → Delete account, or without the app. It's permanent, and it removes your data as described in §13 of the Privacy Policy. Export anything you want to keep first. Deleting the app off your phone doesn't delete the account; that's a separate thing.

Our side. Where you seriously break these Terms, especially §6 and §7, or where the law leaves us no choice, or where what you're doing puts other users, the Service or us at real risk, we may warn you, remove content, limit a feature, suspend the account, or close it. We'll pick the mildest thing that actually works, and unless the breach is severe or keeps repeating, or notice would be unlawful or defeat the point, you'll get told first and given a chance to fix it.

You'll always be told why, and you can push back at [email protected]. The decision gets a proper second look and you get an answer. We may also close accounts with 30 days' notice if the Service shuts down (§13), or accounts left unused for a long stretch, after emailing you about it first.

Once it's over, your licence to use the Service ends immediately. The parts that are meant to outlast the agreement do: §8 on feedback, plus §10, §14, §15, §16, §19 and §20.

18 · When these terms change

These Terms will change now and then, as the app changes and as the law does. The current version is always right here, and the date at the top tells you when it last moved.

For anything material you'll get notice in the app or by email at least 30 days ahead. Don't agree? Close your account before the new version takes effect, at no cost. Keep using the Service afterwards and you've accepted it. Changes forced by law or needed for security can take effect straight away, and we'll tell you as soon as we can.

19 · Which law applies

German law governs these Terms, leaving out the UN Convention on Contracts for the International Sale of Goods and the conflict-of-law rules. If you're a consumer living in the EU, that choice doesn't take away the protection of the mandatory rules where you live.

Jurisdiction follows the ordinary statutory rules. Because GymVim is run by a private individual rather than a registered merchant, we're not agreeing a special place of jurisdiction with you, since § 38 ZPO only allows that between merchants. Consumers can bring a claim where they live, and we'd bring one against a consumer there too.

We're neither obliged nor willing to take part in dispute resolution before a consumer arbitration board under the German Consumer Dispute Resolution Act (VSBG).

On the Digital Services Act: GymVim stores content you create, so it's a hosting service under the DSA, and the share links in §9 mean some of that content can be made public at your request. As a micro enterprise it's exempt from the extra obligations the DSA puts on online platforms (Art. 19 DSA), but the hosting-service duties still apply. In practice that means you can report illegal content to [email protected] and get a decision with reasons, and if we act against your content or your account you'll be told why and can contest it, as §17 sets out.

These Terms, the reporting route above and the appeal route in §17 are what §16 and §17 DSA ask a hosting service for. If you think a decision of ours was wrong, say so and it gets looked at again by a person.

Before anything formal, please just write to [email protected]. Almost everything gets sorted faster that way.

20 · Odds and ends

The whole deal. These Terms, the Privacy Policy, and anything shown to you when you use a specific feature make up the entire agreement about the Service, and they replace whatever came before.

If one part fails. Should a provision turn out to be invalid or unenforceable, the rest carries on, and the broken part is replaced by something lawful that gets as close as possible to what it was meant to achieve.

Not enforcing something isn't giving it up. If we let something slide once, we haven't waived the right to act on it later.

Handing it on. You can't transfer your rights or obligations here without our written agreement. If GymVim itself is ever sold or passed to another operator, including to a company the same developer sets up later, this agreement can move with it, as long as your rights don't shrink. You'll be told beforehand and can close your account if you'd rather not come along.

Things nobody can control. Neither side is liable for failing to perform because of events genuinely beyond its control, for as long as they last.

Language. This is written in English. Any translation is there to help, and the English version governs, except where mandatory consumer law where you live says otherwise.

Notices. We reach you in the app or at your registered email address. You reach us at the addresses in §21.
