Your email address is used for:
Your email is linked to your user identity. It is not used for third-party advertising, sold to data brokers, or shared with anyone for marketing purposes outside our own service.
A unique user identifier (UUID) is assigned to your account by Supabase. It is used for:
Your user ID is linked to your identity. It is not shared with third parties for advertising or tracking.
When you grant notification permission, the app obtains a Firebase Cloud Messaging (FCM) device token. This token is used solely to deliver push notifications to your device, such as:
The device token is linked to your user identity (stored alongside your user ID in our database so we can route notifications to the correct device). It is not used for tracking purposes or advertising. If you deny notification permission, no FCM token is collected.
We use PostHog (self-hosted via the j.performancelens.app proxy) to collect app usage data, including app launches, screen views, and feature interactions. We use Sentry to attach navigation breadcrumbs to crash reports. This data helps us:
App-interaction data is linked to your user identity via PostHog's identify feature. It is not used for advertising, sold to data brokers, or shared with third parties for advertising or tracking purposes.
We use Sentry to collect crash reports when the app encounters an error. Crash data includes stack traces, device model, OS version, and app version. This data is used solely to diagnose and fix bugs.
Crash data is tagged with your user identity to help us debug user-specific issues. It is not used for tracking, advertising, or any non-engineering purpose.
Sentry also collects performance metrics such as app launch time, screen load times, and network request durations. This data helps us monitor and improve app responsiveness.
Performance data is used in aggregate; we do not target individual users with it.
The Android app integrates the following third-party services, which act as data processors on our behalf:
| Service | Purpose | Data Processed |
|---|---|---|
| Supabase | Authentication, database, and serverless edge functions | Email, user ID, trading data, subscription state |
| PostHog | Product analytics (self-hosted proxy) | Email, user ID, app usage events, screen views |
| Sentry | Crash and performance monitoring | Crash logs, breadcrumbs, device info, user ID |
| Firebase Cloud Messaging (Google) | Push notification delivery | FCM device token |
| Stripe | Payment processing (initiated from the web app; not from the Android app) | Stripe customer ID, subscription state — no card details reach our servers |
These services process data under our direction, for purposes we specify, and do not use the data for their own purposes. They are not data-sharing partners within the meaning of Google Play's Data Safety form.
The PerformanceLens Android app does not track you for advertising purposes. Specifically:
All data transmitted between the app and our servers is encrypted in transit using TLS 1.2 or higher. Trading data stored on our servers is additionally encrypted at rest using AES-256-CBC with HMAC-SHA256 integrity protection; the keys are derived per-user and are not held in plaintext on our infrastructure.
We retain your data for as long as your account is active.
You can permanently delete your PerformanceLens account and all associated data at any time. The procedure is described in detail on our Account Deletion page, which is also linked from the app's Google Play store listing. Deletion is processed immediately; backup snapshots that may still contain your data are purged automatically within the standard retention window of our database provider (typically up to 30 days).
Push notification tokens are removed when you sign out, delete your account, or uninstall the app.
You have the right to:
For GDPR, UK GDPR, CCPA, and other regional privacy rights, please see our main Privacy Policy.
The PerformanceLens app is intended for adult users (18 years or older). We do not knowingly collect personal information from children under 18. If you believe a child has provided us with personal data, please contact us at privacy@performancelens.app and we will delete it.
We may update this policy to reflect changes in the app, our processors, or applicable law. We will update the "Last Updated" date at the top of this page when changes are made. Continued use of the app after a change constitutes acceptance of the updated policy.
