Consent to the Processing of Personal Data

Version of 6 October 2026. This is a translation; the Russian version prevails.

I, a user of the RedCalendar app (the “App”), freely, of my own will and in my own interest, give my consent to Artem Andreevich Bolotov (taxpayer ID (INN) 440123579144, support@calendar.red; the “Operator”) to process my personal data, including information about my health, on the terms set out below.

1. What data

• email address; phone number — if the account was created in App version 2.x;
• name or how I would like to be addressed — if entered;
• health information: the start and end dates of my periods, their length and flow, ovulation day, cycle parameters, symptoms, mood and other tags I mark, including tags about my intimate life, day notes;
• technical data: the session identifier on my device, device model, push notification token, time zone, notification settings, app performance and crash data.

2. What for

• creating my account and signing in;
• storing my records and syncing them between my devices;
• predicting periods, ovulation and the fertile window;
• sending notifications about cycle events, unless I turn them off;
• protecting my account;
• answering my requests;
• finding and fixing errors in the App.

3. What actions

Collection, recording, organisation, accumulation, storage, updating (changing), retrieval, use, transfer (provision, access), blocking, deletion, destruction. Processing is automated. Data is stored on a server in the Russian Federation.

4. Who the Operator may engage to process data

I agree that the Operator engages the following parties to process my data, each only to the extent needed for its task:

• Internet-Pro LLC (NetAngels service; 34 Tveritina St, Yekaterinburg, 620026, Russia) — hosting of the server and the database;
• YANDEX LLC (16 Lva Tolstogo St, Moscow, 119021, Russia) and its affiliates providing these services — app performance data (AppMetrica) and sending emails (Yandex Cloud Postbox);
• Quantek LLC (60 Bolshoy Sampsonievsky Ave, lit. A, premises 1-N, Saint Petersburg, 194044, Russia) — the call that confirms the phone number at sign-in;
• Apple Inc. (USA) — delivering push notifications;
• Google LLC (USA) — only for App versions 2.x, until they are shut down.

I agree to the cross-border transfer of my data to Apple Inc. and Google LLC for these purposes.

5. Duration and withdrawal

This consent is valid for as long as my account exists or until I withdraw it. I can withdraw it at any time by deleting my account in the App (Settings → Profile → Delete account) or by writing to support@calendar.red. After withdrawal, the Operator stops processing and destroys the data within the periods set out in the Privacy Policy — no later than 30 days. Withdrawal does not affect processing carried out before it.

6. Age

I confirm that I am at least 14 years old. If I am under 14, this consent is given on my behalf by my parent or other legal guardian.

7. How consent is given

Consent is given electronically: by a confirmation in the App, in an account whose sign-in was verified with a one-time code sent to my email address or a call to my phone number. This confirmation is recognised as a simple electronic signature.

More about how data is processed is in the Privacy Policy.
