Privacy Policy
Mariy Kechyshot app (ru.pirogovlab.mariykechyshot), a PirogovLab project. Effective 16 October 2026.
Data we collect
The app needs no account and does not collect personal data. Calendar, holidays, prayers and omens are built in and work offline. Settings (reminder time, favourites) stay on your device.
Advertising
The app shows ads via the Yandex Mobile Ads SDK (Yandex LLC). The SDK may process the device advertising ID, device information, IP address (approximate location) and ad interaction data to serve and measure ads, under Yandex's policy: yandex.com/legal/confidential. You can reset the advertising ID or opt out of personalisation in Android settings.
"Suggest a holiday / Report a mistake" form
The form is optional. If you use it, your message and any contact you choose to enter (optional) are sent over HTTPS to pirogovlab.ru only to review the suggestion. We do not share it with third parties and delete it on request.
Permissions
Notifications and exact alarms — calendar reminders at the time you choose; run at startup — to keep reminders after reboot; internet — ads and sending the form.
Children
The app is not directed at children under 13 and does not knowingly collect their data.
