Privacy Policy
Last updated November 4, 2026
The short version
- We collect nothing. No account, no email, no analytics, no ads, no tracking.
- It all stays on your phone. What you log is stored only on your device.
- We can't see your data. There is no Nemi server, so there's nothing for us, or anyone, to read, sell or leak.
- Delete anytime. Settings → Delete all data removes everything instantly.
What Nemi stores, and where
Nemi keeps the following in a private database inside the app, on your device only:
- the days you log, with flow, symptoms and any notes you write;
- your cycle and period length settings;
- your reminder choices;
- if you turn on App lock, a scrambled (hashed) version of your Nemi PIN, never the PIN itself.
None of this is sent to us or to anyone else. Nemi has no account system and makes no internet connections with your data.
What Nemi does not collect
Nemi contains no analytics, advertising, crash-reporting or tracking tools. We don't collect your name, email, phone number, location, contacts, device identifiers or usage data. We don't sell or share data, because we never have any.
Face ID, Touch ID and fingerprint unlock
If you turn on biometric unlock, your phone's operating system checks your face or fingerprint and only tells Nemi "yes" or "no". Nemi never sees or stores biometric data.
Reminders
Reminders are scheduled on your phone by your phone; nothing is sent from a server. While App lock is on, reminders on your lock screen only say "You have a reminder in Nemi", so they don't reveal anything to someone glancing at your phone.
Backups, summaries and sharing
Everything that leaves Nemi goes only where you send it, through your phone's share sheet (for example, saving to Files or sending to your doctor).
- Backup & restore makes a backup file locked with a password you choose. Nemi never uploads the file and never sees the password, so it can't recover a forgotten one.
- Export my data makes a PDF summary. Your notes are left out unless you switch them on.
- Share a moment sends only what you see before you share it.
Once you share something, it's handled by the app or person you sent it to.
Phone backups
If you back up your phone (for example iCloud Backup on iPhone, or Google backup on Android), your phone may include Nemi's data in that backup, as it does for most apps. Those backups belong to your Apple or Google account and are handled under their privacy terms. Nemi itself never sends your data anywhere and can't read your backups.
Deleting your data
Settings → Delete all data permanently removes everything Nemi has stored on your phone. Deleting the app does the same. Because we never had a copy, there's nothing for us to delete on our side.
Children
Nemi doesn't collect personal information from anyone, of any age.

Questions? Email privacy@nemicycle.com.
If you email us, for example with Send feedback, we see only what you write and use it only to reply or, if you ask to test Nemi, to invite you to the test. Email to nemicycle.com is received by Cloudflare and kept in our Gmail inbox, and our replies are sent through Brevo. These services only deliver the message; they don't get your cycle data, which never leaves your phone. Ask us any time and we'll delete your email.
If you join our testers group, Google runs it under Google's own privacy policy. We can see members' email addresses and use them only for the test. You can leave the group any time.
