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.
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.
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.
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.
The free version shows ads via Google AdMob (Google LLC). In this process, AdMob may collect and process:
⭐ 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.
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. The website, however, uses Google Analytics 4 with your consent, see Cookies and analytics on this website.
This section is about the website prism-website-three.vercel.app, not the app. The app still ships no analytics SDK. The website uses Google Analytics 4 to understand which pages help people find Prism.
Nothing is stored before you accept. Google Analytics loads in denied mode
(Google Consent Mode v2, analytics_storage: denied). If you reject, or simply

The controller is Matheus Abrahão Martins Alvares. Google LLC acts as processor for Google Analytics 4 data under the Google Privacy Policy and the Google Ads Data Processing Terms. Vercel Inc. acts as processor for hosting and for the cookieless analytics.
Cookies expire on the schedule listed above. Event-level data in Google Analytics 4 follows the retention configured on the property, currently the 14-month default, after which Google deletes it automatically.
Google and Vercel process this data on servers outside the EEA and outside Brazil, including in
the United States. Transfers rely on the European Commission's Standard Contractual
Clauses and on the EU-US Data Privacy Framework, and on the safeguards
of Article 33 of the LGPD. IP addresses are anonymised before storage
(anonymize_ip).
At any time, click “Cookie preferences” in the footer of any page on this site. Withdrawing is as easy as giving consent: the decision takes effect immediately and Google Analytics returns to denied mode. You can also clear the cookies in your browser or install the Google Analytics opt-out add-on.
Since Prism doesn't collect or process personal data on servers, you exercise your rights directly in the app:
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.
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.
