About this app

Alentour is a period and cycle tracker that keeps your data where it belongs: on your phone.

🔒 NOTHING LEAVES YOUR PHONE
No account, no server, no ads, no analytics. What you log is written to a private file on the device, excluded from Google backup. The publisher never receives it. Export everything, erase everything in one gesture: the app then shows you the file is gone.

📅 AN HONEST FORECAST
Your next period is not announced as a certain date but as a window: “between the 14th and the 18th”. It narrows as your cycles look alike and widens when they vary. The app always says how many cycles it relies on, and flags an unusually long cycle (missed entry?) instead of skewing the forecast.

⭕ THE DIAL
Your cycle is a circle you turn with your finger. The day under the marker shows the estimated phase, what you logged that day in previous cycles, and what recurs: “headache 2 days before the period, 4 cycles out of 6”.

✍️ LOG IN SECONDS
Flow, cramps, headaches, mood, energy, sleep, a few words. Saved as you go, even offline.

🔔 DISCREET REMINDERS
A daily reminder and one before your period window, with the text you choose: nothing intimate on the lock screen.

🫣 A LOCK
Fingerprint, face or device PIN on opening. While it is on, the app is hidden in recent apps.

🌙 LIGHT OR DARK
Alentour follows your phone's theme.

Alentour is a tracking notebook. The fertile window shown is a calendar estimate: it is not a method of contraception. The app makes no diagnosis and does not replace medical advice.
