Terms.

The agreement between you and us when you use the app. Training guidance only, not medical advice.

Last updated 24 October 2026

Who we are

Stayer is run by Nikola Stamatovic, Belgrade, Serbia. Email contact@getstayer.com. We answer within 30 days, usually much sooner.

Who can use it

You must be 18 or over. One account per person. Keep your sign-in to yourself, and tell us if you think someone else has used it.

This is not medical advice

Stayer gives general training guidance based on what you tell it. It can't examine you and doesn't diagnose anything. Talk to a doctor before you start endurance training, especially if the health check flagged something. If a pain is sharp, on one side or getting worse, stop and see a physio or doctor.

Your responsibility

You decide what to do each day and accept the risk of doing it. Endurance training can cause injury. Open-water swimming carries a risk of drowning. Never swim alone, and never in conditions you're unsure of.

The community

You're responsible for what you post. Post only your own photos or ones you have permission to share. Nothing unlawful or abusive, and no medical advice presented as fact. By posting you let us show it to other Stayer athletes. It stays yours, and you can delete it. We may remove posts that break these rules and close accounts that keep doing it. Report anything that worries you from the post itself.

Race information

Course details, cut-offs and rules shown here can be out of date. Your race's official athlete guide is the authority. Check it.

Price

Stayer has a free plan and a paid plan, Pro. New accounts get Pro free for 7 days with no card, then move to the free plan unless they choose to pay. Pro is sold by yearly or monthly subscription, which renews until you cancel, or as a Race Pass, one payment for six months that doesn't renew. Payments are taken by Polar Software, Inc., who are the seller on your receipt and charge any sales tax or VAT; the full price including tax is shown before you pay. We'll email you at least 30 days before any price change that affects you. The refunds page sets out what happens if you pay and change your mind.

About 12 weeks before your race, if you're on the free plan, we give you Pro free for 7 days, once per race. It ends by itself and nothing is charged.

Invites: a friend who signs up with your link gets Pro free for 30 days instead of 7. Once they've built a plan, you get 30 days of Pro, for up to 3 friends a year. Rewards earned with fake or duplicate accounts don't count, and we may take them back.

Ending your account

You can delete your account at any time from Settings. We may suspend or close an account that abuses the service or other athletes, and we'll tell you why unless the law stops us.

Liability

We can't promise the service will always be available or correct. As far as the law allows, we aren't liable for injury, lost training, a missed race or other loss arising from its use. Nothing here limits liability for death or personal injury caused by our negligence, for fraud, or for anything else the law doesn't allow us to exclude. If you're a consumer, nothing here affects your legal rights.

Changes to these terms

We'll email you at least 30 days before a change that affects you. If you don't agree, you can delete your account before it takes effect.

Law

If you're a consumer, you can rely on the consumer law of the country you live in and bring a claim in its courts.
