Chekly Privacy Policy

Effective date: October 22, 2026 · Русская версия

Chekly is a mobile app that tracks your spending using electronic receipts from your email. Developer: Aleksandr Altukhov. Contact: chekly-help@yandex.com.

This is a translation of the Russian version of the policy.

What data the app processes

• Addresses of the connected mailboxes — provided by Mail.ru, Yandex or Google when you sign in.
• Access to your mailbox. You sign in on the mail service's own page; the app receives an access key (token) from the service and never sees or stores your password.
• Emails with electronic receipts. The app searches only for messages from senders of cash receipts and does not open any other messages.
• Receipt data: store, date, items, quantities and amounts, receipt details.

Where the data is stored

All data is stored only on your device: receipts in the app's database on the phone, the mailbox access key in the system's secure storage. Chekly has no server of its own: data is not transferred to the developer or third parties, except for the exchange with your mail service (see below), and is not used for advertising. The app contains no analytics or tracking.

The data is used only to show you your spending: totals, purchase categories and receipt history.

The data is kept while the mailbox is connected. It is erased when you disconnect the mailbox, reset all data or delete the app.

Communication with the mail service

The app exchanges data only with your mail service (Mail.ru, Yandex or Gmail) — when you sign in and when it downloads receipt emails. The mail service's privacy rules apply to this exchange.

Data from your Google Account

If you connect a Gmail mailbox, the app receives read-only access to your email from Google (gmail.readonly). It reads only emails with cash receipts and saves the receipt data from them on your phone. This data is not transferred to the developer or third parties and is not used for advertising or for training AI models.

Chekly's use and transfer to any other app of information received from Google APIs will adhere to the Google API Services User Data Policy, including the Limited Use requirements.

You can revoke the app's access to Gmail in your Google Account settings: myaccount.google.com/permissions.

The app does not change anything in your mailbox

The app only reads receipt emails: it does not send, delete or mark anything as read.

How to delete your data

• Settings → “Disconnect” for a mailbox: the access key, the address of that mailbox and its receipts are deleted. For Gmail, the app also revokes its access in your Google Account.
• If two mailboxes are connected, the “Reset all data” button in Settings disconnects both and deletes all receipts.
• Deleting the app from the device deletes all its data.
• You can also revoke the app's access to your mailbox in the security settings of your mail service.

The app's interface is in Russian: “Disconnect” is «Отключить», “Reset all data” is «Сбросить все данные».
