1. Acceptance of Terms
By creating an account, installing the app, or otherwise using the Service, you agree to be bound by these Terms and by our Privacy Policy. If you’re using the Service on behalf of another person, you confirm that you have authority to bind that person to these Terms.
2. Description of Service
Vela is a period- and cycle-tracking application designed around privacy-first, local-first principles. The Service lets you log cycle data, track symptoms and mood, view predictions, and — optionally — sync data across your own devices or share phase context with a trusted partner using end-to-end encryption.
Vela is not a medical device under U.S. Food and Drug Administration regulations, the European Union Medical Device Regulation (EU 2017/745), or the UK Medicines and Healthcare products Regulatory Agency framework. See Section 10 for the full medical disclaimer.
3. Eligibility, Age, and Geographic Availability
You must be at least 16 years old to use Vela. We do not knowingly collect information from anyone under 16. If you believe a minor has provided us information, contact [email protected] and we’ll act promptly.
Geographic availability. Vela is not currently offered in the European Economic Area (EU 27 member states plus Iceland, Liechtenstein, and Norway), the United Kingdom, or Switzerland. The App Store and Google Play listings for Vela are restricted to territories outside those regions. If you are located in a restricted region, please do not attempt to access or use the Service. We may expand availability in the future; any such expansion will be accompanied by the additional disclosures and safeguards required under applicable law (including, where relevant, GDPR Article 27 representation and UK GDPR representation).
4. Accounts and Authentication
Vela works entirely offline. You can use the full app without creating an account. Accounts exist only to enable optional features like cross-device sync and partner mode.
Sign-in methods. If you choose to sign in, you must authenticate using Sign in with Apple or Sign in with Google. We do not offer email-and-password sign-up, and we never create, collect, transmit, or store passwords. Authentication is brokered by our open-source identity library (better-auth), which exchanges a short-lived token with Apple or Google, receives the minimum profile claims they return (a stable provider user ID, and — only if you grant it — your email address or name), and issues a session token for your device. Your data inside the app is indexed by an internal user identifier, never by your email, name, or any other personally identifiable information.
Your responsibility. Because we don’t hold passwords, your account’s security is tied to the security of your Apple ID or Google account. Keep those protected (device passcode, two-factor authentication, recovery options). Notify us immediately at [email protected] if you believe your Apple or Google account — and therefore your Vela session — has been compromised.
5. Subscriptions and Billing
Vela is free to download and use. Some features are available only through a paid subscription (“Vela Premium”). Premium is sold as a monthly, annual, or lifetime plan through the Apple App Store or Google Play Store.
Billing
All payments are processed by Apple or Google (via RevenueCat for subscription management). We never see or store your payment card information.
Free trials
Vela Premium does not currently offer a free trial. If we introduce one in the future, the trial terms (duration, auto-conversion, and cancellation window) will be shown clearly before you subscribe.
Auto-renewal
Monthly and annual subscriptions auto-renew unless cancelled at least 24 hours before the end of the current period. You can manage or cancel your subscription from your device’s subscription settings (App Store / Google Play). Cancelling stops future charges; it does not refund the current period.
Refunds
Refund requests are handled by Apple or Google per their respective store policies. We do not process refunds directly.
Price changes
We may change subscription prices. If we do, we’ll notify you before the change takes effect and give you a chance to accept the new price or cancel.
6. Acceptable Use
When using Vela, you agree not to:
- Reverse engineer, decompile, or attempt to extract source code or encryption keys, except where such restriction is prohibited by law.
- Use the Service to harass, defame, or harm others — including through partner mode.
- Impersonate anyone or misrepresent your affiliation with any person.
- Interfere with, disrupt, or attempt to gain unauthorized access to the Service or its infrastructure.
- Use the Service in any way that violates applicable law.
7. Partner Mode
Partner Mode lets you share selected phase or cycle context with one trusted partner (“Partner”). These additional rules apply:
- Age. Both you and your Partner must be at least 16 years old.
- Consent. You decide what to share. Your Partner sees only what you explicitly enable; nothing more.
- Revocation. You may revoke the Partner’s access at any time from app settings. On revocation, the Partner’s cached data must be cleared from their device upon next app launch, and no new data will be transmitted to them.
- Partner obligations. A Partner who receives shared information agrees to use it only in the context you intended and not to redistribute, export, or use it to harm, coerce, or surveil you.
- No responsibility for misuse. We cannot control how a Partner behaves with shared data. If a Partner misuses information, that is a matter between you and them; we provide the revocation tool but are not liable for their conduct.
- Abuse reporting. If a Partner is coercing you into sharing or misusing shared data, revoke immediately and, if it helps, contact [email protected]. We will support your ability to revoke access and will not re-enable it without your request.
8. Intellectual Property and Feedback
The Vela name, logo, visual design, source code, and all other materials we create are owned by danestves LLC and protected by copyright, trademark, and other laws. We grant you a limited, non-exclusive, non-transferable, revocable license to use the Service for personal, non-commercial purposes in accordance with these Terms.
Feedback license. If you send us suggestions, ideas, or feedback about the Service, you grant us a worldwide, royalty-free, perpetual, irrevocable license to use, reproduce, modify, and incorporate your feedback into our products without obligation or compensation to you.
9. Your Content
Everything you log in Vela — your cycle entries, symptoms, notes, journal, partner context — is your content. You own it. Because Vela is architected around local-first storage and zero-knowledge encryption, we do not access, read, or analyze your health data on our servers. The encrypted copy we may store for sync is cryptographically opaque to us.
You grant us a narrow, automatic license to store and transmit the encrypted version of your data solely to operate the Service (e.g., to relay it between your devices during sync). This license ends when you delete your data or your account.
10. Medical Disclaimer and Non-Device Status
Vela is not medical advice. Predictions, insights, anomaly detections, and suggestions in the app are informational only. They are not a substitute for consultation with a licensed healthcare professional. Do not rely on Vela for contraception, conception planning, or the diagnosis or treatment of any medical condition.
Vela is designed and intended for general wellness purposes as defined by the U.S. Food and Drug Administration’s guidance on “General Wellness: Policy for Low Risk Devices.” Vela is not:
- A medical device within the meaning of the U.S. Federal Food, Drug, and Cosmetic Act.
- A medical device under the European Union Medical Device Regulation (EU 2017/745).
- A medical device under the UK Medicines and Healthcare products Regulatory Agency framework.
- A product subject to the U.S. Health Insurance Portability and Accountability Act (HIPAA). We are not a “covered entity” or “business associate” under HIPAA.
If you think you may have a medical emergency, call your doctor or emergency services immediately. Your use of Vela is at your own risk.
11. Export Controls and Sanctions
Vela incorporates cryptographic software (AES-256-GCM encryption and X25519 key exchange). You represent and warrant that:
- You are not located in, under the control of, or a national or resident of any country subject to a comprehensive U.S. embargo (currently Cuba, Iran, North Korea, Syria, and the Crimea, Donetsk, and Luhansk regions).
- You are not listed on any U.S. Government list of prohibited or restricted parties, including the Specially Designated Nationals List or Denied Persons List.
- You will not export, re-export, or transfer the Service in violation of U.S. or other applicable export control laws.
12. Apple and Google Store Terms
If you download Vela from the Apple App Store, you acknowledge that these Terms are between you and danestves LLC, not Apple, and that Apple is not responsible for the Service or its content. Apple has no obligation to provide maintenance or support. Apple is a third-party beneficiary of these Terms and may enforce them against you. Your use of the Service must also comply with the Apple Licensed Application End User License Agreement.
If you download Vela from Google Play, you acknowledge that your use is also subject to the Google Play Terms of Service.
13. Disclaimers and Limitation of Liability
The Service is provided “as is” and “as available,” without warranties of any kind, express or implied, including but not limited to warranties of merchantability, fitness for a particular purpose, and non-infringement. We do not warrant that the Service will be uninterrupted, error-free, or secure against every possible threat.
To the fullest extent permitted by law, in no event shall danestves LLC, its affiliates, or its contributors be liable for any indirect, incidental, special, consequential, or punitive damages — including lost profits, lost data, or personal injury — arising out of or related to your use of the Service. Our total liability for any claim arising from these Terms or the Service shall not exceed the amount you paid us in the twelve (12) months preceding the claim, or USD $50, whichever is greater.
14. Indemnification
You agree to indemnify and hold harmless danestves LLC and its team from any claims, damages, liabilities, and expenses (including reasonable legal fees) arising from your violation of these Terms, your misuse of the Service, or your violation of any third-party right.
15. Governing Law, Dispute Resolution, Class Action Waiver
Governing law. These Terms are governed by the laws of the State of Delaware, United States, without regard to its conflict-of-laws rules.
Informal resolution first. Before filing any formal claim, you agree to try to resolve the dispute informally by emailing [email protected] with a clear description of the problem and the resolution you’re seeking. We’ll try to resolve the matter within 30 days. Only if we can’t resolve it during that period may either party proceed to formal action.
Venue. Any dispute not resolved informally shall be brought exclusively in the state or federal courts located in Delaware, unless applicable consumer-protection law grants you a mandatory right to another forum.
Class action waiver. To the fullest extent permitted by law, you and we each waive any right to bring or participate in a class, collective, or representative action, and each agree that any dispute will be resolved on an individual basis. You and we also waive any right to a trial by jury.
16. Electronic Communications
By using the Service, you consent to receive communications from us electronically — including by email (if you have provided one), in-app notices, and messages posted on hellovela.app. You agree that all such electronic communications satisfy any legal requirement that communications be in writing.
17. Changes to These Terms
We may update these Terms from time to time. When we do, we’ll update the “Last updated” date above and, for material changes, notify you through the app or by email (if we have one for you). Continued use of the Service after the change takes effect constitutes acceptance of the updated Terms.
18. Termination
You can stop using Vela at any time by uninstalling the app. If you have an account, you can delete it from within the app — this wipes your data from our servers and revokes your keys.
We may suspend or terminate your access if you violate these Terms or pose a risk to other users or the Service. We’ll notify you when reasonable and possible.
19. Miscellaneous
Entire agreement. These Terms, together with the Privacy Policy, are the entire agreement between you and danestves LLC regarding the Service.
Severability. If any provision is found unenforceable, the remainder stays in effect.
No waiver. Our failure to enforce a right is not a waiver of that right.
Assignment. You may not assign these Terms. We may assign them to a successor in connection with a merger, acquisition, or similar transaction.
Force majeure. We are not liable for delays or failures to perform resulting from causes beyond our reasonable control, including acts of God, natural disasters, war, terrorism, labor disputes, and internet or power outages.
Language. The authoritative version of these Terms is English. Where translations are provided and differ, the English version controls.
