Your phone dies. Your laptop gets stolen. Your cognitive performance history shouldn't die with it.

What's New

Thalen accounts are here. Sign in with just your email. No password to remember or reset. A magic link arrives, you click it, and you're in.

Once signed in, you can enable cross-device sync. Your test sessions, supplement logs, and settings follow you across devices. Take a test on your phone during lunch. Review the results on your desktop that evening.

Sync is disabled by default. Your data stays local until you explicitly turn it on.

What Syncs

Everything that matters:

Test sessions and raw trial data
Supplement dose logs and custom stacks
UI preferences like view modes

What doesn't sync: computed baselines and cached insights. Those rebuild automatically from your raw data. Less to transfer, same results.

Privacy by Design

We built sync the way we'd want it built for ourselves.

Opt-in only. The toggle is off when you create an account. You choose whether to enable cloud backup. Many users will never need it.

Self-serve deletion. Want your server data gone? One button. No support ticket. No waiting. Your local data stays untouched.

Two ways to disable. Keep your cloud backup as insurance, or delete everything. Your call.

How It Works

Sync happens automatically when you open the app. Changes push up, new data pulls down. A timestamp shows your last sync. If you have pending changes, you'll see that too.

Conflicts between devices resolve simply. For append-only data like test results, the latest write wins. For editable data like supplement stacks, we track versions per device.

Getting Started

Tap Account in the dashboard
Enter your email and check your inbox
Click the magic link
Toggle on Cloud Sync if you want it

That's it. No password. No verification codes. No friction.

Bottom Line

Your cognitive data is valuable. Now it's portable and protected. Use sync if you want backup and multi-device access. Don't use it if you prefer everything local. Either way, the choice is yours.
