Privacy Policy – My Fin

Last updated: September 22, 2026

1. Introduction

My Fin is a personal finance management application developed by Antonio Alencar Velozo ("the developer").

This Privacy Policy explains how information is handled when you use the application.

2. Data Stored on Your Device

My Fin lets you register and organize personal financial information, including but not limited to:

• financial transactions and recurrences;
• accounts, banks and account types;
• people, assets, cost centers and purposes (categories);
• application settings.

This information is stored only on your device. It is not sent to the developer or to any server.

3. Data Collection

My Fin does not require account creation and does not collect personal data for marketing, advertising or resale purposes.

The only data that leaves your device is the purchase information described in section 8, and the receipt lookup described in section 7, which happens only when you ask for it.

4. Data Sharing

Your financial records are never shared with third parties, sold, or used for advertising.

5. Backup and Export

The application provides backup, restore, export and sharing features. These operations are started only by you, and the generated files are saved or shared wherever you choose.

You are responsible for protecting and securely storing those files.

6. Camera, Photos and Imported Files

My Fin can read a bank statement that you choose (OFX, CSV or PDF, including scanned PDFs) and a receipt that you photograph or pick from your gallery. All of this reading happens on your device:

• the file or photo is opened only after you select it;
• text recognition uses Google Play services on the device itself, without an internet connection and without sending the image anywhere;
• the app does not keep the photo or a copy of the file. It keeps only the values you confirm, such as date, amount, description and, for a receipt, the code printed on it, which is used to warn you if the same receipt is read twice;
• the camera permission is requested only when you choose to photograph a receipt.

7. Receipt Lookup on Tax Authority Websites

A fiscal receipt often carries a QR code with the address of its official page on a tax authority website. When such a code is read, My Fin offers a button to look that page up and fill in the store, date, amount and items.

This lookup is optional and happens only when you tap that button. The app asks for your agreement before the first lookup and remembers your answer; declining simply leaves the feature unused.

• what leaves your device is only the address printed on the receipt, which contains the receipt identifier and the store tax identification;
• none of your records, and nothing that identifies you, is sent;
• the address is only opened when it belongs to an official government site, and always over a secure (HTTPS) connection;
• the website you consult is operated by the tax authority, and its own privacy practices apply to that visit.

Apart from this lookup and the purchase processing described in section 8, the application does not use the internet.

8. Free Plan and In-App Purchases

My Fin can be used for free within quantity limits (for example, a number of transactions per month). MyFin Pro, available as a monthly or yearly subscription or as a one-time lifetime purchase, removes those limits. The limits are checked on your device, using the records stored there.

Purchases are processed by Google Play. The developer does not receive or store your payment details, such as card numbers.

To validate purchases and keep track of your access to MyFin Pro, the application uses RevenueCat, a subscription management service provided by RevenueCat, Inc. RevenueCat receives:

• a random, anonymous identifier generated by the app (not linked to your name, email or financial records);
• purchase information provided by Google Play, such as the product purchased, transaction identifiers, dates, price, currency and store country;
• basic technical information needed to deliver the service, such as app version, operating system and device model.

This information is used only to provide and restore your purchases and to produce aggregated sales reports for the developer. Your financial records are never sent to RevenueCat.

For more details, see the RevenueCat Privacy Policy and the Google Privacy Policy. Subscriptions can be managed or cancelled at any time in the Google Play subscriptions settings.

9. Other Third-Party Libraries

The application uses open-source libraries for its technical operation. Apart from the purchase processing described above, they do not send your data to third parties.

10. Security

Reasonable measures are taken to protect the information handled by the application. However, no electronic storage or transmission method is completely secure, and absolute security cannot be guaranteed.

11. Data Retention and Deletion

Financial records (stored only on your device). They are deleted immediately when you delete them in My Fin, clear the app data in your device settings, or uninstall the application. The developer holds no copy of them.

Purchase information held by RevenueCat. To request its deletion:

1. Send an email to aalencarvz@gmail.com with the subject "My Fin - data deletion request".
2. Include the Google Play order number of your purchase (it starts with "GPA." and is shown in the purchase receipt email and in Google Play under Payments & subscriptions), so the purchase can be located.
3. You will receive a confirmation within 30 days, once the purchase information associated with that order has been deleted from RevenueCat.

What is deleted: the anonymous app identifier and the purchase and subscription records associated with it in RevenueCat. After deletion, a previous purchase can still be restored in the app through "Restore Purchases", which creates a new record.

What is kept: the order and payment records held by Google Play, which are governed by the Google Privacy Policy, and any record the developer is legally required to keep for accounting or tax purposes, only for the period required by law.

12. Children's Privacy

The application is not specifically directed toward children under the age of 9.

13. Changes to This Policy

This Privacy Policy may be updated from time to time. The latest version will always be available on this page, with the date of the last update at the top.
