Terms of Service

End User License Agreement (EULA) for the sovv iOS application.

Operated by Mustafar Ltd. · Effective 22 May 2026 · Last updated 22 May 2026.

These Terms ("Terms" or "Agreement") form a binding contract between you ("you") and Mustafar Ltd. ("we", "us", "our") governing your access to and use of the sovv iOS application and any related services (collectively, the "Service"). The Service is operated under the brand sovv at sovv.health. By creating an account, downloading the application, or starting a free trial you confirm that you have read, understood, and agreed to be bound by these Terms.

Important — not medical advice. sovv is a fitness and recovery analytics product. It is not a medical device. It does not diagnose, treat, cure, or prevent any disease or condition. If your Apple Watch flags elevated breathing disturbances or anything else that concerns you, talk to a qualified clinician. Do not stop or change any prescribed treatment based on something sovv told you.

1. Who can use sovv

You must be at least 18 years old (or the age of majority where you live) to create an account. The Service is intended for adult athletes training for hybrid-racing or comparable events. Do not use the Service while operating a vehicle, machinery, or doing anything else that requires your full attention.

2. Your account

You are responsible for the security of your sign-in credentials and for everything that happens under your account. Tell us at support@sovv.health as soon as you suspect unauthorised access. You may close your account at any time from Profile → Privacy & Data → Delete account & wipe data.

3. The free trial and subscription (sovv Pro)

sovv Pro is offered as an auto-renewing subscription with two SKUs available through the Apple App Store:

Monthly — billed once per calendar month at the price shown in the App Store (currently US $14.99 / month).
Annual — billed once per calendar year at the price shown in the App Store (currently US $119.99 / year — a saving of approximately 33% versus monthly).

Both SKUs include a 7-day free trial for first-time subscribers. The trial automatically converts into a paid subscription at the end of the 7-day period unless you cancel at least 24 hours before it ends.

3.1 Auto-renewal

Your subscription renews automatically for the same term and at the same price (subject to §3.2) unless you cancel at least 24 hours before the renewal date. Apple charges your iTunes / Apple ID account at confirmation of purchase and again at each renewal. You can review or cancel the subscription at iOS Settings → Apple ID → Subscriptions.

3.2 Price changes

If we change the subscription price, Apple will notify you and prompt you to confirm the new price before the next renewal. If you do not confirm, your subscription will not renew.

3.3 Refunds

Subscription purchases are managed and billed by Apple. Refund requests are handled by Apple via reportaproblem.apple.com. We do not have the ability to process refunds on Apple's behalf.

3.4 What Pro unlocks

Pro entitles you to the overnight processing engine, the morning briefing, the Focus Index, race-aware periodisation, the Apple Watch glance, and any other Pro-tier feature in the version of sovv installed on your device. Features in development or labelled "beta" may change without notice. Discontinuation of the Service is governed by §9.

4. Acceptable use

You agree not to:

Reverse engineer, decompile, disassemble, or attempt to derive the source code of the Service except to the extent that applicable law expressly permits;
Circumvent the subscription gate (including any DEBUG-only "Force Pro" toggle in development builds, which is provided solely for our internal use);
Use sovv to provide a competing service or to train a third-party machine-learning model;
Resell, sublicense, or share your account credentials;
Use the Service in any manner that could disable, overburden, damage, or impair it;
Use any robot, spider, or other automated means to access the Service for any purpose without our express written permission;
Use the Service for any unlawful purpose or in any way that breaches applicable law;
Rely on sovv's outputs in a way that would harm yourself or others (see the medical-advice notice above).

5. Your data

How we handle your data is governed by the Privacy Policy, which is incorporated into these Terms by reference. In short: your health, training, sleep, and nutrition data never leaves your device.

6. Intellectual property

The Service, including its overnight processing engine, design system, scoring heuristics, semantic knowledge graph, and underlying code, is owned by Mustafar Ltd. and is protected by copyright, trade-secret, and patent law — including, without limitation, Intellectual Property Office of Singapore patent application 10202601003R. The sovv name, the sovv monogram, and the sovv.health name are trademarks of Mustafar Ltd. These Terms grant you a limited, non-exclusive, non-transferable, revocable, non-sublicensable licence to use the Service on Apple devices that you own or control, for your personal, non-commercial use. Nothing in these Terms transfers ownership of any intellectual property to you.

7. Third-party services

sovv uses Firebase Authentication (Google LLC) for sign-in, Open Food Facts (open-data, public-domain) for barcode lookups, and Apple's StoreKit for subscriptions. Your use of those services is also governed by their respective terms.

8. Disclaimers & limitation of liability

The Service is provided "as is" and "as available". To the maximum extent permitted by applicable law, Mustafar Ltd. disclaims all warranties, express or implied, including the implied warranties of merchantability, fitness for a particular purpose, and non-infringement.

sovv is not a substitute for professional medical advice. The Service may be unavailable, interrupted, or inaccurate. Decisions about training, nutrition, recovery, sleep, or medical care are yours alone.

To the maximum extent permitted by applicable law, our total cumulative liability arising out of or relating to these Terms or the Service will not exceed the greater of (a) the amount you have paid us for the Service in the 12 months immediately preceding the event giving rise to the claim, or (b) US $100. We will not be liable for indirect, incidental, special, consequential, exemplary, or punitive damages, including loss of profits, loss of revenue, or loss of data, even if advised of the possibility of such damages. Some jurisdictions do not allow the exclusion or limitation of certain damages — in those jurisdictions our liability is limited to the maximum extent permitted by law and the rest of these Terms remains in effect.

9. Termination & discontinuation

You may stop using the Service at any time. We may suspend or terminate your account if you materially breach these Terms. We may also discontinue the Service or any feature of it on reasonable notice — if Pro features are discontinued during an active paid subscription term we will provide a pro-rata refund via Apple where required by applicable law.

10. Apple-required terms (EULA disclosures)

The following provisions apply because the Service is licensed through the Apple App Store. They are required by Apple's App Store Review Guidelines for any app that does not adopt Apple's standard end-user licence agreement.

These Terms are between you and Mustafar Ltd. only, and not with Apple. Mustafar Ltd., not Apple, is solely responsible for the Service and its content.
The Service is licensed, not sold, to you. Your licence is limited to a non-transferable licence to use the Service on Apple-branded products that you own or control, as permitted by the Apple Media Services Terms and the Usage Rules set out in those terms.
Apple has no obligation whatsoever to furnish any maintenance and support services with respect to the Service.
In the event of any failure of the Service to conform to any applicable warranty, you may notify Apple, and Apple will refund the purchase price for the Service (if any). To the maximum extent permitted by applicable law, Apple will have no other warranty obligation whatsoever with respect to the Service. As between Apple and Mustafar Ltd., any other claims, losses, liabilities, damages, costs or expenses attributable to any failure to conform to any warranty will be Mustafar Ltd.'s sole responsibility.
Mustafar Ltd. and you acknowledge that Apple is not responsible for addressing any claims you or any third party have relating to the Service or your possession and use of the Service, including (a) product liability claims, (b) any claim that the Service fails to conform to any applicable legal or regulatory requirement, and (c) claims arising under consumer-protection, privacy, or similar legislation.
In the event of any third-party claim that the Service or your possession and use of the Service infringes that third party's intellectual property rights, as between Apple and Mustafar Ltd., Mustafar Ltd. — not Apple — will be solely responsible for the investigation, defence, settlement and discharge of any such intellectual-property infringement claim.
You represent and warrant that (a) you are not located in a country that is subject to a U.S. Government embargo, or that has been designated by the U.S. Government as a "terrorist supporting" country, and (b) you are not listed on any U.S. Government list of prohibited or restricted parties.
You must comply with applicable third-party terms of agreement when using the Service.
Apple and Apple's subsidiaries are third-party beneficiaries of these Terms, and upon your acceptance of these Terms, Apple will have the right (and will be deemed to have accepted the right) to enforce these Terms against you as a third-party beneficiary thereof.

11. Governing law & disputes

These Terms are governed by the laws of Singapore, without regard to its conflict-of-laws rules. Any dispute arising out of or in connection with these Terms or the Service is subject to the exclusive jurisdiction of the courts of Singapore, except where mandatory consumer-protection laws in your country of residence grant you a non-waivable right to bring proceedings in your local courts.

12. Changes to these Terms

We may update these Terms from time to time. When we do, we will update the "Last updated" date at the top of this page and surface the change in-app on next launch. Material changes will be announced at least 30 days before they take effect; if you do not agree to the updated Terms, you must stop using the Service before the changes take effect.

13. General

These Terms, together with the Privacy Policy, constitute the entire agreement between you and Mustafar Ltd. concerning the Service and supersede all prior and contemporaneous agreements. If any provision of these Terms is held unenforceable, the remainder will continue in full force and effect. Our failure to enforce any provision is not a waiver of our right to do so later. You may not assign these Terms; we may assign them in connection with a merger, acquisition, or sale of substantially all our assets.
