Terms of Service
Who we are. Custom Gains is operated by TaaviTaavi OÜ, registry code 12569372, a company registered in Estonia ("we", "us"). By creating an account or using the service you agree to these terms. If you do not agree, please do not use Custom Gains. Questions: taavi@customgains.fit.
What Custom Gains is
Custom Gains is an AI training coach. You describe what you are training for, and the coach builds structured, multi-sport training plans, adapts them to the activities and recovery data you choose to share, and — if you connect a compatible watch — can publish sessions to it.
The plans are generated by software, not by a human coach. They are general fitness guidance based on the information available to the coach. They are not supervised instruction, and no qualified professional reviews each plan before you see it.
Health and safety
Custom Gains does not provide medical advice. Nothing in the service is a diagnosis, treatment, or a substitute for advice from a doctor or other qualified health professional.
Exercise carries inherent risks, including serious injury. Consult a physician before starting or significantly changing a training programme, particularly if you have a medical condition, are pregnant, are recovering from injury, or have been inactive. Stop training and seek medical help if you feel unwell. You decide which sessions to attempt and you train at your own risk.
Your account
You need an account to use Custom Gains. Give accurate details, keep your password to yourself, and tell us promptly if you think someone else has access. You are responsible for what happens under your account. You must be at least 16 years old.
Connected services
Custom Gains works alongside third-party platforms — most importantly Garmin Connect, and payment processing by Stripe. Connecting them is optional and always your choice, and you can disconnect at any time from within the app.
We are an independent product. We are not affiliated with, endorsed by, or sponsored by Garmin Ltd. or its subsidiaries, and Garmin trademarks belong to their owners. Those platforms have their own terms and privacy policies, they control their own availability, and we cannot guarantee that a connection will keep working if a provider changes or withdraws access. What happens to your personal data is described in our Privacy Policy.
Trials, subscriptions and payment
- Free trial. New accounts get a free trial. No card is required to start it.
- Subscriptions. Paid plans are billed in advance and renew automatically each period until you cancel. Prices are shown in the app before you pay, including any applicable VAT.
- Cancelling. You can cancel at any time from the billing portal. Cancellation stops the next renewal; you keep access until the end of the period you have already paid for.
- Founder pricing. Where a plan is offered as a founder rate, that rate stays fixed for as long as the subscription remains continuously active. Cancelling ends it.
- Payments. Payments are handled by Stripe. We do not store your card details.
- Changes. We may change prices, but not for a period you have already paid for. We will give reasonable notice before a change affects you.
Right of withdrawal (EU consumers)
If you are a consumer in the EU you normally have 14 days to withdraw from a distance contract. Because Custom Gains is digital content supplied immediately, by subscribing you ask us to start the service straight away and acknowledge that you lose the right of withdrawal once it has been fully performed. This does not affect your statutory rights where the service is faulty. If something has gone wrong with your subscription, email us — we would rather sort it out than argue about it.
Acceptable use
Please do not: use the service unlawfully; resell or redistribute the plans as your own coaching product; share your account with others; attempt to break, overload, scrape or reverse-engineer the service; interfere with other users; or use it to harm anyone. We may suspend accounts that do these things.
Your content and our content
You keep ownership of the information you put into Custom Gains — your goals, messages, and the training and health data you connect. You grant us the permission needed to operate the service for you: to store that information, process it, and generate your plans. We use it as described in the Privacy Policy.
The software, brand and design of Custom Gains stay ours. The training plans generated for you are yours to use for your own training.
Availability
We work to keep Custom Gains running, but we do not promise uninterrupted service. Maintenance, third-party outages and faults happen. We may change or discontinue features; if we discontinue the service altogether, we will give reasonable notice and will not charge you for a period you cannot use.
Ending these terms
You can stop using Custom Gains and delete your account at any time. We may suspend or close an account that breaches these terms, or where we are required to. If we close your account without cause, we will refund the unused part of any period you have paid for.
Liability
Custom Gains is provided "as is". To the extent the law allows, we are not liable for indirect or consequential loss, lost profits, lost data, or for injury arising from training you chose to undertake. Where we are liable, our total liability is limited to the amount you paid us in the twelve months before the claim.
Nothing here limits liability that cannot be limited by law — including death or personal injury caused by our negligence, fraud, or your mandatory rights as a consumer.
Changes to these terms
We may update these terms. We will post the revised version here and update the "Last updated" date; where a change materially affects you we will tell you in advance.
Law and disputes
These terms are governed by Estonian law, and disputes go to the courts of Estonia. If you are a consumer, you keep the protection of the mandatory law of the country you live in, and you may use the European Commission's online dispute resolution platform at ec.europa.eu/odr.
