1. Who provides Cyli
Cyli and cyli.app are provided by Sule Arslan ("Cyli", "we", "us"), an individual provider reachable at support@cyli.app. Privacy and data-rights requests may be sent to that address, and a postal address is supplied on request to anyone with a legitimate need for it. This policy applies in all Apple territories and is effective 2026-09-21.
2. Health and wellness information in the app
Cyli lets you choose whether to enter setup answers and records such as period dates and flow, symptoms, mood, energy, sleep, pain, medication selections and notes. These records are processed and stored in encrypted local app storage on your device. Cyli does not create an account and does not send those records to Cyli, an advertising company or a health-data backend.
Cyli does not enable HealthKit, advertising, tracking, third-party analytics or third-party crash reporting. It does not sell health information or use it for advertising. Manual encrypted export/import and automatic cloud backup/restore are not available in this release. Cyli does not store personal health information in iCloud.
If your release includes the Cyli Apple Watch companion, selected health records, bounded technical identifiers and delivery status may be transferred directly between your paired iPhone and Apple Watch using authenticated encrypted communication. Cyli does not receive that content on a backend and the transfer is not a cloud backup.
3. Local retention, deletion and recovery
Local records remain on the device until you edit or delete them, use Delete all local Cyli data, or the operating system removes the app data. Cyli has no account or server-side health record to delete. Local deletion does not delete information you independently send by email or retain outside the app. Device loss, deletion, corruption, key loss, reinstall or unsupported migration may cause permanent data loss. Cyli does not promise remote wipe or recovery.
4. Website information
cyli.app has no account, contact form, advertising, analytics or tracking. It may store only your light/dark theme choice in your browser as a functional preference; that value contains no health information and is not used for tracking.
GoDaddy shared hosting in the United States; security and access logs kept no longer than 30 days.
5. Support and privacy communications
If you email us, we receive the sender address, message, attachments you choose to include and ordinary email metadata. We use that information to respond to your request, troubleshoot and protect the product, handle privacy or accessibility requests, and comply with applicable law. Do not include health details. If you send health information despite this warning, we limit access and delete it when it is no longer needed to handle the request or comply with law.
name.com forwarding to a Google-hosted mailbox read only by the provider.
We retain support and privacy correspondence for no longer than 12 months after closure or last action, delete it earlier when it is no longer needed where permitted, and retain only what an applicable legal obligation or documented legal hold requires.
6. Children and eligibility
Cyli is intended for people aged 13 or older. It does not knowingly operate a child account or behavioral-advertising profile. The App Store age rating describes app content; it does not replace this eligibility rule or any parental-consent requirement in an applicable market.
7. Rights, transfers and complaints
You normally control app health records by editing or deleting them in the app. For information sent to support or processed in website security logs, you may ask us to exercise the rights available under applicable law by contacting support@cyli.app. We use request information only to verify and answer the request and do not ask for health details as identity proof. You may also complain to the competent data-protection authority where applicable.
The verified providers and processing locations described above may involve processing outside your country. We will use any transfer mechanism and safeguards required by the law that applies to the selected launch markets.
8. Security, changes and contact
We use proportionate technical and organizational safeguards, but no device, email or internet service is completely secure. We will update this policy when material practices change and provide any notice required by applicable law. Contact support@cyli.app for privacy questions.
