Privacy Policy for FinLet

Last updated: July 15, 2026

1. Who we are

FinLet ("we", "us", or "the app") is a financial-literacy learning app for children, designed to be used together with a parent or guardian. This policy explains what information the app handles and how. If you have questions, contact us at leon130853@gmail.com.

2. Information stored on your device

The following is created and stored locally on your device only (using the device's local storage). It is not sent to us or uploaded to any server for storage:

• The child's first name (optional, entered during setup)
• In-app virtual balance, chores, savings goals, and transaction history (play money only — no real money is involved)
• Quiz progress, streaks, badges, stars, and penguin customization
• Chat history with the in-app AI mentor
• The parent PIN used to open the parent area
• App preferences (language, etc.)

Because this data lives on the device, removing it is fully in your control (see "How to delete data" below).

3. Information sent to our server and AI provider

FinLet includes an AI mentor (a friendly penguin) and an automatically generated quiz. To make these work, the app sends certain content to our own server (api.getfinlet.com), which forwards it to our AI provider, Anthropic PBC (the Claude API), to generate a response:

• AI mentor chat: the messages your child types, plus a short summary of in-app progress (such as the play-money balance, savings goals, number of chores and lessons completed) and, if provided, the child's first name for personalization.
• Quiz generation: the chosen quiz topic, difficulty, and language. No personal information is included in quiz requests.

This content is sent only at the moment a reply or quiz is generated. We do not store these messages on our server; we relay them and return the AI's answer. Anthropic processes the request to generate the response and handles the data under its own privacy terms. Per Anthropic's API policy, API inputs are not used to train its models by default.

We use a technical access token so that only the FinLet app can use our server; this token is not personal information about you.

3a. Safety filtering and reports

To keep the AI mentor safe for children, our server checks messages before and after they reach the AI provider:

• Blocked before sending. If a message appears to describe self-harm, violence, adult topics, meeting strangers, or if it contains contact details such as a phone number, e-mail address, or home address, the message is not sent to Anthropic at all. The app answers locally with a safe, supportive message that points your child to a trusted adult.
• Checked after generating. AI replies are screened before being shown, and unsuitable replies are replaced with a safe message.
• What we log. When the filter triggers we record only the category of the trigger and the time — never the text your child wrote.

Every AI reply has a report button. If your child reports a reply, we receive the reported AI reply, the chosen reason, and the app language, and we store them so we can improve the filter. Reports do not include your child's name or any device identifier. If you would like a report deleted, write to us at the address in section 11.

4. What we do NOT do

• We do not require registration, accounts, email addresses, or phone numbers.
• We do not collect precise or coarse location.
• We do not include third-party advertising, and we do not show ads.
• We do not use third-party analytics or tracking SDKs.
• We do not sell or rent personal information to anyone.
• We do not collect advertising identifiers or build advertising profiles.

5. Third-party services

The only third party that receives content from the app is Anthropic PBC, which provides the AI that powers the mentor chat and quiz generation. You can review Anthropic's privacy practices at anthropic.com/legal/privacy.

6. Children's privacy (COPPA and similar laws)

FinLet is intended for children and is meant to be set up and supervised by a parent or guardian. We designed the app to minimize data: nearly everything stays on the device, and there are no accounts, ads, or trackers.

By setting up the app and entering an optional first name, the parent or guardian consents to the limited processing described in Section 3 (sending chat messages and a progress summary to our AI provider to generate replies). If you prefer not to share your child's first name with the AI provider, you may simply leave the name blank during setup — the app works fully without it.

We do not knowingly collect more personal information from children than is described here. A parent or guardian may review and delete the app's data at any time (see below), or contact us at the email above with any request.

7. Parental controls and how to delete data

• Parent area: protected by a PIN, where a parent manages chores, approvals, the child's name, and settings.
• Reset progress: the "Reset progress" button inside the app erases all locally stored data (name, balances, chores, goals, quiz progress, chat history) and returns the app to first-run state.
• Uninstalling the app removes all locally stored data from the device.

8. Data retention

Data stored on your device is kept until you reset progress or uninstall the app. Content sent for AI replies is not retained on our server; our AI provider retains and processes it only as described in its own policy.

9. Security

Communication between the app and our server uses encrypted HTTPS. No method of storage or transmission is 100% secure, but we take reasonable measures to protect the limited information the app handles.

10. Changes to this policy

We may update this policy from time to time. Material changes will be reflected by updating the "Last updated" date at the top of this page.
