Privacy Policy

Last updated: 19 October 2026

Your cycle data stays on your device

Dates, logs, symptoms and the forecasts derived from them are stored in your device's local storage. There is no account, no sign-up, and no server they sync to. We cannot see them either.

Notifications are built on your device

The forecast and the notifications are computed on the device. The text of a notification is never routed through a server of ours and contains nothing that leaves the phone.

What does leave: purchases

Apple processes the purchase. To verify ownership and restore access, Apple and RevenueCat process technical purchase information and an installation or customer identifier created for the purchase service. An identifier can connect requests from the same installation even when it contains no name. Cycle records, symptoms and forecasts are not sent for purchase verification.

What does leave: crash reports

Sentry receives technical crash and unresponsiveness reports to help diagnose faults. Reports may include an installation identifier, device and OS details, app version and diagnostic information. The service may also process an IP address and derive a general location from it. These reports are not guaranteed to be fully anonymous. Cycle records, symptoms and forecasts are excluded. Diagnostics are separate from the optional usage-measurement preference.

What does leave: product measurement

App usage measurement requires your opt-in. It is off by default. Turn it on or off in Your Data, even without a purchase. Importing a backup turns it off and requires a fresh choice.

Turning this off stops future collection and discards locally queued events. It does not delete information already sent or cancel requests already in flight. Purchase verification and crash reporting are separate from this choice.

To understand which screens help and which do not, we use a service called PostHog. It receives technical events only, such as "log saved" or "purchase completed". No cycle date, symptom, phase or forecast value is ever sent, neither as the content of an event nor as its name.

Earlier attribution integrations

Earlier app builds included AppsFlyer. The current app no longer includes that integration. Removing an integration does not delete information previously received by the vendor; contact us for help with questions about earlier data.

What does leave: aggregate usage data

If you have allowed the app store to share analytics, we see anonymous aggregate reports: how many downloads, how many crashes, and so on. No individual can be identified from them. You can turn this off in your device settings.

This website

The marketing site measures traffic with PostHog, so we can tell which pages work. It is cookieless: the identifier lives in the browser tab and is gone when you close it, which is why there is no consent banner and nothing to follow you between visits. The site handles no cycle data at all.

No ads, and nothing sold

We show no advertising inside the app and sell your data to nobody. Apple provides aggregate acquisition reports; these do not add an attribution SDK to the app.

Deletion

Your Data lets you delete local cycle and symptom records and cancels Achoti reminders scheduled for them. We have no server copy of your cycle records. This action does not delete files you previously exported or shared, or existing device backups. You can restore information from a suitable backup you kept. Purchase and technical information already sent to service providers has a separate lifecycle governed by their policies and applicable law.

Age

The app is intended for ages 13 and up. If you are under 18, read this policy with an adult.

Your rights

Under Israel's Protection of Privacy Law, 5741-1981, you have the right to review and correct information held about you. Because cycle data is held only on your device, reviewing and deleting it happens in the app. For purchase and measurement data held by Apple, RevenueCat and PostHog, contact us and we will help.

Changes to this policy

If the policy changes we will update the date at the top. A material change will also be shown inside the app.
