Privacy at Peak Flow

Last updated September 2026

Peak Flow is operated by Peak Human Inc., Brampton, Ontario, Canada. This page explains what we collect, where it lives, and what we do with it, in plain language.

What we collect

• Your account: name, email, and profile photo if you sign in with Google, or email and password if you sign up directly.
• Test results: the timing and scoring data from each reaction-time, impulse-control, and interference test you take.
• Training sessions: when you trained, for how long, and the tap-and-probe events from the session.
• Screen-time entries you type in or confirm, and the Screen Time screenshots you upload.
• Daily logs: your focus rating, sleep, caffeine, exercise, and notes.
• Voice recordings, if you choose to record the guided-session phrases in your own voice.

We do not use tracking pixels, advertising identifiers, or third-party analytics inside the app.

Where it's stored

Your data is held in a database and file storage run on our behalf by Lovable Cloud (built on Supabase). Access is enforced at the database level: every table and every uploaded file is locked to the account that created it. No other user can read your data under any circumstances, and the app itself has no "view everyone's results" mode.

Uploaded screenshots are read once by an AI service (Google Gemini, via Lovable's gateway) to pre-fill the screen-time form. The extracted numbers are shown to you for confirmation; nothing is saved until you confirm.

Sharing with the Peak Human platform

Peak Flow is built by Peak Human. When you complete a test (reaction time, impulse control, or interference), the result is also sent to the main Peak Human platform, where it contributes to your Brain domain score if you hold a Peak Human membership. This is the only place your Peak Flow data goes. Your attention-training sessions, screen-time entries, daily logs, screenshots, and voice recordings are not shared with the platform or with anyone else. We do not sell data, and we do not share it with advertisers or data brokers.

Your control

We keep your data for as long as your account exists. From Settings you can export everything we hold about you, or delete your account. Deletion removes your rows from every table and your files from storage immediately; it cannot be undone. Data already contributed to your Peak Human Brain score is governed by the Peak Human platform's own privacy policy.

What this app is not

Peak Flow measures how your attention performs day to day. It is not a medical device and does not diagnose ADHD, dementia, concussion, or any other condition. A single result mostly reflects sleep, time of day, and practice — look at the trend, not the number. If you're worried about your memory or concentration, talk to your physician.
