Vela — Terms of Use

Last updated 9 June 2026

These Terms of Use ("Terms") govern your use of the Vela mobile application ("Vela", the "App"). Vela is a private, offline-first period and cycle tracker provided by an independent developer ("we", "us", "our"). By downloading, installing, or using the App, you agree to these Terms. If you do not agree, do not use the App.

1. Acceptance of Terms

By installing or using Vela, you confirm that you have read, understood, and agree to be bound by these Terms and by any policies referenced here, including our Privacy Policy.

You confirm that you are old enough to form a binding contract in your jurisdiction and are legally permitted to use the App. If you use Vela on behalf of a minor in your care, you accept these Terms on their behalf and are responsible for their use.

If you do not agree to any part of these Terms, your only remedy is to stop using the App and delete it from your device.

2. About Vela and Your Data

Vela helps you record menstrual periods, view cycle predictions and ovulation estimates, and log moods and notes. All data you enter is stored locally on your device. There is no Vela account, no sign-up, no login, and no Vela-operated server or backend. We never receive, see, or transmit your data to our own servers.

Vela offers optional features that you control: iCloud backup via Apple's CloudKit private database (syncing only between your own devices through your personal Apple account, where we cannot access it); two-way sync of periods and moods with Apple Health, on-device and only with your explicit permission; local reminder notifications scheduled on your device with no push server; importing dates from a Flo PDF export or a screenshot, read locally on your device via on-device processing; and exporting your history as a PDF that you control.

Vela contains no analytics, no advertising, no third-party trackers, and no components that sell, share, or transmit your data. Your reproductive and health information stays under your control and never leaves it except through Apple services (iCloud, Health) that you enable and that operate under your own Apple account.

3. Not a Medical Device — Important Health Disclaimer

Vela is provided for personal informational and self-tracking purposes only. It is not a medical device and is not intended to diagnose, treat, cure, monitor, or prevent any disease or health condition.

Cycle predictions, ovulation estimates, fertile-window indications, and any other calculations are estimates based on the data you enter. They are inherently uncertain and may be inaccurate. They are NOT a method of contraception, NOT a means of achieving or preventing pregnancy, and NOT a substitute for professional medical advice, diagnosis, or treatment.

Do not rely on Vela for birth control, family planning, or any medical decision. Always consult a qualified healthcare professional regarding your health, symptoms, fertility, or any questions you may have. Never disregard or delay seeking professional medical advice because of information provided by the App.

4. License to Use the App

Subject to these Terms, we grant you a personal, limited, non-exclusive, non-transferable, non-sublicensable, revocable license to download and use one copy of the App on devices you own or control, solely for your own personal, non-commercial use.

You may not copy, modify, distribute, sell, rent, sublicense, or lease the App; reverse engineer, decompile, or disassemble it except to the extent that applicable law expressly permits; remove or alter any proprietary notices; or use the App in any unlawful manner or for any unlawful purpose.

This license does not grant you any ownership rights in the App. All rights not expressly granted are reserved by us.

5. Your Responsibilities and Data Backup

You are responsible for the accuracy of the information you enter and for any decisions you make based on the App. You are responsible for keeping your device, screen lock, and Apple account secure, as access to your device may grant access to your Vela data.

Because all data is stored locally on your device, you are solely responsible for backing it up. If you delete the App, reset, lose, or replace your device, or do not enable iCloud backup, your data may be permanently lost. We cannot recover any data for you because we never hold it.

We strongly recommend enabling iCloud backup and periodically exporting your history so you retain copies you control.

6. Third-Party Services

Optional features rely on Apple services, including iCloud / CloudKit and Apple Health. Your use of those services is governed by Apple's own terms and privacy policies, not by us. We do not control and are not responsible for the availability, security, or behavior of Apple's services or your Apple account.

Your access to and use of the App through the Apple App Store (and, where applicable, Google Play) is also subject to that store's terms. Where these Terms conflict with Apple's App Store Terms of Service with respect to your use of the App obtained from the App Store, Apple's terms govern to the extent of that conflict.

You acknowledge that Apple is not a party to these Terms and is not responsible for the App or its content; any claim relating to the App is between you and us, not Apple, except as required by applicable App Store terms.

7. Intellectual Property

The App, including its software, design, text, graphics, logos, and the Vela name, is owned by us or our licensors and is protected by intellectual property and other laws.

The data and content you create and store in the App belong to you. We claim no ownership of your personal entries, and because your data stays on your device, we have no access to it.

You may not use our trademarks, branding, or any part of the App's protected content without our prior written permission.

8. Disclaimer of Warranties

The App is provided "AS IS" and "AS AVAILABLE", without warranties of any kind, whether express, implied, or statutory. To the maximum extent permitted by law, we disclaim all warranties, including implied warranties of merchantability, fitness for a particular purpose, accuracy, reliability, and non-infringement.

We do not warrant that the App will be uninterrupted, error-free, secure, or free of defects, or that any prediction, estimate, calculation, import, export, sync, or reminder will be accurate, complete, timely, or reliable.

Some jurisdictions do not allow the exclusion of certain warranties, so some of the above exclusions may not apply to you.

9. Limitation of Liability

To the maximum extent permitted by applicable law, in no event will we be liable for any indirect, incidental, special, consequential, exemplary, or punitive damages, or for any loss of data, loss of profits, loss of goodwill, personal injury, or any damages arising from health, fertility, or reproductive decisions, however caused and under any theory of liability, even if advised of the possibility of such damages.

To the maximum extent permitted by law, our total aggregate liability arising out of or relating to the App or these Terms will not exceed the greater of the amount you paid for the App (if any) or USD 10.

Nothing in these Terms excludes or limits any liability that cannot lawfully be excluded or limited, including, where applicable, liability for death or personal injury caused by negligence or for fraud. Some jurisdictions do not allow certain limitations, so some of the above may not apply to you.

10. Termination

These Terms apply for as long as you use the App. You may terminate them at any time by ceasing to use and deleting the App from your device.

We may suspend or terminate your license if you breach these Terms or if required by law. Sections that by their nature should survive termination — including intellectual property, disclaimers, limitation of liability, and governing law — will continue to apply.

On termination, the license granted to you ends and you must stop using the App. Deleting the App will not remove copies of data you have already backed up or exported, which remain your responsibility.

11. Changes to the App and to These Terms

We may update, modify, or discontinue the App or any feature at any time, with or without notice. We are not obligated to provide updates, support, or maintenance.

We may revise these Terms from time to time. When we do, we will update the "Last updated" date above and make the revised Terms available within the App or its store listing. Material changes will be made available before they take effect where required by law.

Your continued use of the App after revised Terms take effect constitutes your acceptance of them. If you do not agree, stop using and delete the App.

12. Governing Law

These Terms and any dispute arising out of or relating to them or the App are governed by the laws of Ukraine, without regard to its conflict-of-laws rules.

Subject to any mandatory consumer-protection rights available to you in your country of residence, you agree to submit to the exclusive jurisdiction of the courts located in Ukraine for the resolution of any dispute.

If any provision of these Terms is found unenforceable, the remaining provisions will remain in full force and effect.

Because Vela stores your data only on your device and we hold no copy of it, we cannot access, retrieve, or delete your personal entries on your behalf.

Thank you for using Vela, and for trusting a tracker built to keep your data private and in your control.
