For Gimbal: ADHD Test & Focus · Updated: September 12, 2026

1. What to include

The more of this you send, the faster we can help:

• Your device model and operating system version (for example iPhone 14, iOS 19.2)
• The Gimbal version, from Settings → About
• What you did, what you expected, and what happened instead
• A screenshot or screen recording if the problem is visible
• For purchase problems: the store (App Store or Google Play), the approximate date, and whether it was a subscription or the lifetime purchase

Please do not send screenshots of your answers or results unless they are part of the problem — we do not need them and would rather not hold them.

2. Your data

Where is my data kept?

In a database on your phone, inside the app's private storage. It is never uploaded to us. There is no account, so there is nothing for us to look up. See the Privacy Policy.

I deleted the app / lost my phone. Can you restore my results?

No, and this is worth being blunt about: we hold no copy, so there is nothing to restore. The only way your data survives a lost device is a device backup you made yourself — see Your Data & Deletion.

How do I delete everything?

In the app: Settings → delete all data. This erases every answer, result, note, task and session from the device. Uninstalling the app also removes the local database. Details, including how to clear it from device backups, are on the Your Data & Deletion page.

Does Gimbal sync between my phone and tablet?

No. Without an account there is no sync. Each install keeps its own separate data.

I am moving to a new phone.

Restoring the new device from a backup of the old one usually brings Gimbal's data across. A fresh install on a new device starts empty. Pro is separate from your data — it is tied to your store account and comes back with Restore purchases.

3. Gimbal Pro

I paid but Pro is not unlocked.

First try Restore purchases in Settings, with the device online and signed in to the same store account you bought with. If it still does not unlock, email us with the store, the date and the product you bought, and we will sort it out.

How do I cancel a subscription?

• iOS: Settings → your name → Subscriptions → Gimbal → Cancel Subscription
• Android: Google Play → profile icon → Payments & subscriptions → Subscriptions → Gimbal → Cancel

Deleting the app does not cancel a subscription. You keep Pro until the end of the period you already paid for.

Can I get a refund?

Refunds are handled by the store, not by us: reportaproblem.apple.com for Apple, or the Google Play refund form. Tell us what happened as well — if it was our bug, we will back your request.

I bought Pro on iPhone. Does it work on my Android phone?

No. Apple and Google hold separate receipts and neither can see the other's purchases.

4. The tests

My score changed a lot between two attempts. Is it broken?

Probably not. Attention performance moves with sleep, stress, caffeine, time of day, medication and how noisy the room is. That variability is exactly why Gimbal favours repeat measurements over a single result: the trend across several sessions says more than any one score.

Does my phone affect the results?

Slightly. Screen refresh rate and touch latency differ between devices, which is why comparisons within your own history on the same device are the meaningful ones. Take tests in a quiet place, holding the phone the same way each time, with notifications silenced.

Can Gimbal tell me whether I have ADHD?

No. It is a screening and self‑assessment tool, not a diagnostic one. Please read the Medical Disclaimer, and take results that concern you to a qualified professional.

5. The app

• Languages: Gimbal is available in 13 languages and follows your device language when it is one of them.
• Offline: everything except buying or restoring Pro works with no connection at all.
• Notifications: optional, and configurable in Settings and in your device settings.
• Accessibility: if something in the app is hard to use with larger text, reduced motion or a screen reader, tell us — include the screen and what got in the way, and we will treat it as a bug.

6. Bugs, feature requests and security

Bug reports and feature requests are welcome at contact@muzo.dev. If you believe you have found a security or privacy vulnerability, write with "Security" in the subject line and describe the issue and how to reproduce it; please give us a reasonable chance to fix it before publishing details. We will confirm receipt within 3 business days.

7. Privacy requests

For access, deletion or other data requests, email contact@muzo.dev with "Privacy request" in the subject line. Data on your device is already yours to delete at any time; the only records we can act on are purchase validation records. We answer formal requests within 30 days. See the Privacy Policy, section 11.
