Privacy Policy

Last updated April 30, 2026

What data we collect

We collect the information you provide when you use StackProof. This includes your email address, the supplements you log, the experiments you create, and the daily health and symptom entries you record in the app.

We also collect limited device and technical information such as device type, operating system, app version, and basic diagnostic data needed to keep the service secure and working properly.

How we use your data

We use your data to provide the StackProof experience, including saving your experiments, calculating baseline and active-phase comparisons, showing results, and supporting account features such as syncing across devices.

We do not use your data for advertising, and we do not sell your personal information.

Data storage

StackProof stores application data using Supabase. Data is encrypted in transit and encrypted at rest. We use reasonable administrative, technical, and organizational safeguards to protect your information.

Third party services

We use Supabase to host and store app data. We use RevenueCat to manage subscriptions and payment status for Pro features.

These providers only receive the information needed to perform their services for StackProof.

Data retention

We keep your data while your account is active so you can access your experiment history. If you delete your account, we will delete your data from our active systems within 30 days, unless we need to keep limited information for legal, security, or fraud-prevention reasons.

Your rights

You can request access to your data, request an export of your data, or ask us to delete your data. We will respond to reasonable privacy requests in accordance with applicable law.
