Plan
Standard plan
Standard keeps all core tests free with occasional ads. PRO removes ads and unlocks full history and extended modes (planned).

PRO plan (planned)
PRO is designed as a simple upgrade on top of the free version: same tests, but more control, no ads, and extended modes for heavy users.
Current plan: Standard plan
What PRO will include
- No banner ads on tests and result pages.
- Full history on this device – not just truncated snapshots.
- Extended modes (longer blocks, harder variants, more trials).
- Early access to new tasks and beta experiments.
- More granular statistics and export options.
All core tests will stay free. PRO is aimed at people who test regularly and want “lab-style” control.
On this browser
For development and testing you can locally mark this browser as PRO or revert back to Standard.
This uses a small flag in local storage (gmt_pro_flag) that the site reads.
This does not process any payments – it is a local switch only. Real billing will be integrated later.
Data & privacy controls
Use these tools to manage what is stored on this device: local test results, settings and the small flags used for UI (like PRO).
Export or import your local test data
You can export the shared store used on this device (gmt_store) as a JSON file.
It includes per-test arrays of results, timestamps and a basic profile object.
Export lets you analyse results in a spreadsheet or keep a backup.
Import can restore a previous gmt_store file to this browser.
Clear local test results
This will remove:
gmt_store– shared store with “Your results”.- Per-test local histories (e.g. reaction test tables).
- Local PRO flag (
gmt_pro_flag).
This does not delete your cloud account. It only affects this browser.
Global statistics
Global statistics (total visits / tests) are stored separately on the server in fully aggregate form. They are used to keep benchmarks fresh and never include personal identifiers.
Security & account
Your cloud account is handled by Firebase Authentication. You can sign in with Google or email and password, and reset your password any time.

Sign in via the top-right “Log in” button. Once signed in, you can securely delete your account below.
Reset password (email accounts)
If you use email/password instead of Google login, you can trigger a reset link from the log-in window (top-right) – the same as on the home page.
Delete account
This option permanently deletes your cloud account (Firebase Authentication user) linked to your email / Google login. It does not touch your local browser data unless you also clear it above.
Requirements:
- You must be currently signed in.
- For security reasons, Firebase may require you to log in again just before deletion.
If you see a message about “recent login required”, simply log out, sign in again, then return to this page and repeat the deletion.
