Private apps for every stage, from period to parenthood.
Cycella is a family of four apps: a period tracker, a pregnancy record, a baby log and an app for her partner. None asks who you are, none shows ads, and your records stay on your phone.

- Encrypted on her phone first, so we cannot read it
- She can pause or stop at any time
How the apps work together
Each app stands on its own. When you want, they pass along just what is needed, and nothing more.
- 1Your cycle
Cycella predicts your period and fertile days from your own logs.
- 2Pregnancy
Cycella Pregnancy keeps your weeks, visits and questions.
- 3Your baby
Cycella Baby takes the birth details from Pregnancy in a locked file.
- +Your partner
Cycella Partner shows only the items you tick, so they can help.
One promise across all four
These apps see some of the most sensitive data on your phone. Ours are built so there is less of it to leak or sell in the first place — read what we checked before designing them this way.
No account needed
None of the apps ask for your name, email or phone number. Your records live on your phone.
Encrypted before it leaves
Backup and partner sharing are off until you turn them on. Both are encrypted on your phone before anything is sent, and our server never gets the key, so we can't read them. How it works.
No ads, no selling data
There are no ads and no trackers in any Cycella app. We don't sell or share your data with anyone.
