Privacy Policy

Your privacy is a priority. Prism was designed to be private by default, putting you in full control of your data. This policy describes how Prism handles (or rather, does not handle) your data, in compliance with the LGPD (Brazilian Law No. 13.709/2018), the GDPR (EU 2016/679), and Apple's guidelines.

🔒 Your data is yours: your subscription information stays exclusively on your device. The free version shows ads via Google AdMob, which may collect limited device data for personalization. Prism Pro subscribers get an ad-free experience with no third-party collection.

What we do NOT collect

  • Subscription data: names, amounts, and dates stay only on your device.
  • Financial data: we have no access to what you spend or save.
  • Personal identification: we don't collect your name, email, or phone. There's no login.
  • Location: the app neither requests nor accesses your location.

Local storage

All your data is stored locally on your iPhone or iPad with SwiftData, Apple's native framework, protected by the system's encryption (Data Protection) and the app's sandbox. Prism does not sync your data with any server of ours.

Permissions requested

Notifications (optional)

Used only to remind you of upcoming renewals. They're processed locally, without external servers. They can be disabled at any time in Settings > Prism > Notifications.

Ad tracking, ATT (optional)

Prism may request tracking permission (App Tracking Transparency) so that Google AdMob can show more relevant ads. You can decline without any impact on functionality, the ads simply become less personalized.

Advertising (Google AdMob)

The free version shows ads via Google AdMob (Google LLC). In this process, AdMob may collect and process:

  • Advertising Identifier (IDFA): only if you authorize it via ATT.
  • IP address: for approximate geolocation and regional ads.
  • Device information: model, system, and version.
  • Ad interaction: clicks and views.

⭐ Prism Pro: subscribers get an ad-free experience. No data is shared with Google AdMob for Pro users.

AdMob handles data in accordance with Google's Privacy Policy. Manage your preferences in Google Ad Settings.

Data sharing

Prism does not share your subscription data with third parties. Your financial information stays exclusively on your device. Beyond Google AdMob (free version), the app does not contain analytics SDKs, behavior trackers, or social media integrations.

Your rights (LGPD & GDPR)

Since Prism doesn't collect or process personal data on servers, you exercise your rights directly in the app:

  • Access: all your data is always visible in the app.
  • Rectification: edit any subscription at any time.
  • Erasure: delete subscriptions in the app or uninstall it to erase everything.
  • Objection: we don't perform profiling or automated decision-making.

Minors

Prism does not intentionally collect data from minors. Since we don't collect any personal data, the app is safe for users of all ages.

International transfers

Prism does not transfer your subscription data. When you use the free version with ads, Google AdMob may process device data on servers in different countries, in accordance with Google's Privacy Policy.
