Privacy Policy

Last updated: 11 November 2026

AI Balance is an open-source app published by KRSLYS BV, a company registered in Belgium, that shows how much of your AI subscriptions you have used. This policy covers the desktop apps and the Android and iOS apps.

The short version

• AI Balance has no server. Nothing you do in the app is sent to KRSLYS BV.
• Your sign-ins and API keys stay on your device and are sent only to the provider they belong to.
• The app has no analytics, no crash reporting and no tracking of its own.
• The Android and iOS versions from the app stores may show a small ad. The ad network, not KRSLYS BV, receives the data that ads need. See Advertising.

What the app stores on your device

• Accounts you add: the provider, the name shown on the card, and the credential (an OAuth token or an API key). Credentials are kept in the operating system's keychain on desktop, and in the app's private storage on Android and iOS.
• Your last usage numbers and your settings, so the app can show them when it opens.

Removing an account deletes its credential. Uninstalling the app deletes everything.

What the app sends, and to whom

To show your usage, the app talks directly to the providers whose accounts you add: Anthropic (Claude), OpenAI (ChatGPT), Cursor, GitHub (Copilot), Moonshot AI (Kimi), xAI (Grok), Amp, OpenCode, Meta (Muse Code), Windsurf (Devin), OpenRouter, Z.ai and Ollama. Each request carries only that provider's own credential. Each provider handles the request under its own privacy policy.

To tell you about a new version, the app reads the public list of releases from GitHub a few times a day. That request carries no information about you or your accounts, and you can turn it off in Settings.

The app sends nothing to KRSLYS BV or to anyone else.

Advertising

This section applies only to versions of the app that show ads (Android and iOS, from the app stores). The desktop apps never show ads.

• Ads are provided by Google AdMob. To show and measure ads, Google may collect your device's advertising identifier, IP address, approximate location derived from it, device and app information, and how you interact with ads. See how Google uses information from apps that use its services.
• Where the law requires it, the app asks for your consent before personalized ads are shown, and on iOS before any tracking. You can decline, and the app works the same.
• You can reset or delete your advertising identifier, or turn off ad personalization, in your device's settings.
• The ad network never receives your accounts, credentials or usage numbers.
• KRSLYS BV sees only what the ad network reports in total, such as how many ads were shown. That report does not identify you.

Your rights in the EU, the EEA and the UK

This section applies once a version of the app shows ads, because only then is personal data processed on the developer's behalf.

• Who is responsible: KRSLYS BV, [registered address], Belgium, company number (KBO/BCE) 1026.902.574, info@krslys.be. For ads, Google is responsible together with the developer for the data its ad service collects.
• Why and on what basis: to show and measure ads, on the basis of your consent (Article 6(1)(a) GDPR). Storing or reading the advertising identifier on your device also needs your consent.
• Your choice: you are asked before any ad data is collected. Saying no does not limit the app. You can change your answer at any time under Settings.
• Where the data goes: Google may process it outside the EU, including in the United States, under the EU-US Data Privacy Framework and standard contractual clauses.
• How long: the developer keeps none of it. Google keeps it for the periods in its own policy.
• Your rights: access, correction, deletion, restriction, portability, objection, and withdrawing consent. Because the developer holds no data about you, requests about ad data go to Google; the developer will help you reach the right place.
• Complaints: you can complain to the data protection authority of the country where you live. For Belgium that is the Gegevensbeschermingsautoriteit / Autorité de protection des données (https://www.dataprotectionauthority.be).

Children

AI Balance is a tool for people who pay for AI subscriptions. It is not directed at children under 13, and it does not knowingly collect data from them.

Changes

Changes to this policy are published in this file. Its history is public in the app's repository.
