Privacy Policy — Simple Ovulation Calendar

Effective July 4, 2026 · Operated by GooseApp LLC, a Maryland limited liability company (“we”).

The short version: your cycle data stays on your device. We don’t have accounts, we don’t collect your name or email, and we don’t sell data.

What stays on your device

The dates you enter, your cycle length, your entry history, and what your reminder dates mean are stored in your browser’s local storage on your device. We cannot read them. Deleting your browser data (or removing the app) deletes them.

What we store if you turn on reminders

To deliver a scheduled push notification, our server stores: your device’s anonymous push address and its delivery keys, the bare dates you asked to be reminded on (with no labels — our server does not know what a date means), and your timezone. Nothing else — no name, no email, no identifier tied to you. Tap “Stop notifications” and this record is deleted. If your device stops accepting pushes, the record is deleted automatically.

Notifications are deliberately discreet

Reminder text is coded (for example, “📅 Reminder — Peak day today.”) and never includes health details.

What we don’t do

No advertising, no analytics SDKs, no data sales, no sharing with third parties except our hosting provider (Vercel, which processes standard web server logs to serve the site).

Your choices

Everything is optional. Clear your browser data to erase local data; unsubscribe to erase server data. Questions: hello@gooseapp.ai.

Changes

We’ll update this page and change the date above.
