Terms of Service

Last updated: November 12, 2026

These Terms of Service ("Terms") govern your use of the TextFit mobile app and this website (together, the "Service"), provided by 01 Apps ("we", "us"), registration number 307473546, of Pilėnų g. 45A-1, LT-36237 Panevėžys, Lithuania. By using the Service, you agree to these Terms. If you don't agree, please don't use the Service. Our Privacy Policy explains how we handle your data.

1. The Service

TextFit is an AI endurance coach for running, cycling, swimming and strength. From the information you give it, it builds and adjusts a week-by-week training plan, talks with you in the coach chat, puts planned workouts on your Garmin watch (through Garmin Connect) or Apple Watch, and reads your completed activities and recovery data from Garmin or Apple Health to assess your workouts, form and recovery. The coach requires a TextFit Pro subscription (section 7) and your AI consent (section 6).

Earlier version. Some people still use an earlier version of the app (version 1.x), which turns a single workout you describe in plain text into a structured workout and can send it to intervals.icu or Apple Watch. Parts of these Terms that apply only to that earlier version are marked as such.

2. Health and safety — not medical advice

TextFit is a training-planning tool. It is not a medical device and does not diagnose, treat, prevent or monitor any disease or medical condition. Plans, workouts, assessments, recovery verdicts and everything else the coach says are general training information, not medical advice, and are not a substitute for advice from a doctor, physiotherapist or other qualified professional.

• Consult a physician before you start any training program or change your training significantly — especially if you have a heart condition or other medical condition, an injury, are pregnant, take medication, or haven't exercised for a while.
• The coach only knows what you tell it and what your devices record. It doesn't know your medical history, and device data (heart rate, HRV, sleep, power, pace) can be inaccurate.
• You decide whether, how and when to do any workout. Adjust or skip it if it doesn't feel right. Stop exercising and seek medical help if you feel chest pain, faintness or dizziness, unusual shortness of breath, or other worrying symptoms. In an emergency, contact your local emergency services.
• Training involves a risk of injury. You train, and perform any workout the Service suggests, at your own risk.

3. AI-generated content

The coach's plans, replies and assessments — and, in the earlier version, converted workouts — are generated by AI and can be incomplete, inaccurate or unsuitable for you. We check the coach's plan changes against training rules, but we can't guarantee they are correct. Review what the coach suggests before you act on it; every change the coach makes is shown in the chat and can be undone. Don't rely on the Service for decisions about your health.

4. Eligibility

You must be at least 16 years old to use TextFit. By using the Service, you confirm that you meet this requirement.

5. Your account

TextFit creates an anonymous account on your device when you first open the app — no sign-up is required. You're responsible for keeping your device secure, since it's what anchors your account. You can delete your account and all associated data at any time in Settings in the app; see our Privacy Policy (section 10) for what that removes. Deleting your account or the app doesn't cancel a subscription (section 7).

6. AI consent

The coach runs on an AI provider (OpenAI). To use it, you must give explicit consent in the app to sending your profile, plan, activities, coach chat and recovery data to that provider, as described in the consent screen and our Privacy Policy (section 4). You can withdraw consent at any time in Settings → AI consent. While it is off, the coach can't plan, adjust your plan or reply; your data stays, and you can turn consent back on at any time. Withdrawing AI consent doesn't cancel or pause your subscription.

7. TextFit Pro, free trial & billing

The coach and its features require TextFit Pro, an auto-renewing subscription sold through the Apple App Store and Google Play. You can complete onboarding and see a preview of your first plan before you subscribe.

• Prices. Pro is offered monthly or yearly. The price and billing period for your country and currency are shown in the app before you buy (in the US, currently US$14.99 per month or US$99.99 per year).
• Free trial. New subscribers may get a 14-day free trial. Trial eligibility is decided by Apple or Google and is limited to one free trial per subscription group, so you may not be eligible if you had a TextFit trial before (including in the earlier version). Any unused part of a free trial ends when you buy a paid subscription.
• Payment. Payment is charged to your Apple ID or Google Play account when you confirm the purchase or, with a free trial, when the trial ends — unless you cancel at least 24 hours before the trial ends.
• Auto-renewal. Your subscription renews automatically at the same price and period unless you cancel at least 24 hours before the end of the current period. Your account is charged for renewal within the 24 hours before the period ends.
• Cancelling. Manage or cancel your subscription at any time in your App Store account settings (iPhone Settings → your name → Subscriptions), in Google Play (profile icon → Payments & subscriptions → Subscriptions), or via Manage subscription in TextFit's Settings. Cancelling takes effect at the end of the current period.
• Refunds. Refunds for App Store purchases are handled by Apple, and for Google Play purchases by Google, under their own policies.
• When Pro ends. Without an active subscription or trial, the app is locked: the coach, plan changes and automatic sending of workouts to your watch stop, while Settings stays available. Your data is kept, and everything resumes if you subscribe again.
• Earlier subscriptions. If you subscribed to Pro in the earlier version, your subscription continues under these Terms. If you bought Pro on our website, your card was charged by our payment processor (Stripe, through RevenueCat); manage or cancel it via the link in your receipt email, and contact support@textfit.app about refunds.

We may change prices or the features included in Pro. Price changes for existing subscriptions follow the App Store's or Google Play's rules, including any notice and consent Apple or Google requires.

8. Earlier version: free tier & usage limits

In the earlier version, free accounts include a limited number of workout conversions and saves per month; Pro accounts get higher limits. We may change these limits from time to time. The current version has no free tier.

9. Devices and third-party services

TextFit works with Garmin Connect, Apple Health, Apple Watch (WorkoutKit) and the Apple App Store, and the earlier version with intervals.icu. These services are provided by third parties under their own terms, which you're responsible for reviewing and complying with. Workouts we send to Garmin Connect are also subject to Garmin's terms and privacy policy. We're not responsible for the availability, accuracy or conduct of any third-party service, and a change on their side may limit what TextFit can do. Garmin and Garmin Connect are trademarks of Garmin Ltd. or its subsidiaries; Apple, Apple Watch and Apple Health are trademarks of Apple Inc.

10. Acceptable use

You agree not to:

• use the Service for any unlawful purpose, or to submit content that is illegal, abusive, or infringes someone else's rights;
• try to make the coach produce harmful content or act outside its purpose, or misuse the AI features in ways that breach our AI provider's usage policies;
• attempt to reverse-engineer, decompile, or interfere with the Service or its security;
• access the Service through automated means, or abuse or overload it;
• misrepresent your identity or impersonate anyone else.

We may suspend or terminate access for accounts that violate these Terms.

11. Ownership

You keep ownership of what you write and the data you bring — your messages, training text, profile and device data. By submitting it, you grant us a license to process it (including sending it to our AI provider, with your AI consent) solely to provide the Service to you. You may use the plans and workouts the Service generates for your own training. TextFit, its branding and its underlying software are owned by 01 Apps and protected by applicable intellectual property laws.

12. Disclaimers

The Service is provided "as is" and "as available," without warranties of any kind, express or implied, including fitness for a particular purpose, accuracy, or non-infringement. We don't guarantee that plans, workouts or assessments are error-free or safe for you specifically, that workouts will reach your watch on time, or that the Service will be uninterrupted.

13. Limitation of liability

To the fullest extent permitted by law, 01 Apps will not be liable for any indirect, incidental, or consequential damages — including personal injury arising from performing a workout — arising from your use of the Service. Our total liability for any claim relating to the Service is limited to the amount you paid us in the 12 months before the claim arose, if any. Nothing in these Terms limits liability that can't be limited by law, or your statutory rights as a consumer.

14. Termination

You may stop using the Service and delete your account at any time. We may suspend or terminate your access if you violate these Terms. Sections that by their nature should survive termination (e.g. Health and safety, Ownership, Disclaimers, Limitation of Liability) will continue to apply.

15. Apple App Store terms

If you downloaded TextFit from the Apple App Store, Apple's Licensed Application End User License Agreement (Standard EULA) also applies to your use of the app, together with these Terms. You also acknowledge that:

• these Terms are between you and 01 Apps only, not Apple, and Apple has no obligation to provide maintenance or support for the Service;
• to the extent any warranty applies and the app fails to conform to it, you may notify Apple, and Apple will refund the purchase price (if any); Apple has no other warranty obligation for the app;
• Apple is not responsible for any product claims, including that the Service fails to meet applicable legal or regulatory requirements, or for any third-party claim that the app infringes someone's intellectual property rights;
• 01 Apps, not Apple, is responsible for addressing any claims relating to the Service or your use of it;
• Apple and its subsidiaries are third-party beneficiaries of these Terms and may enforce them against you.

16. Governing law

These Terms are governed by the laws of Lithuania, without regard to its conflict-of-law principles. Any dispute arising from these Terms or the Service will be subject to the exclusive jurisdiction of the courts of Lithuania, except where mandatory consumer-protection law gives you the right to bring a claim in your own country of residence.

17. Changes to these Terms

We may update these Terms from time to time. When we do, we'll revise the "Last updated" date at the top of this page, and for material changes we'll make a reasonable effort to notify you in the app. Continuing to use the Service after a change means you accept the updated Terms.
