Terms of Service
Last updated: 30 June 2026
These terms govern your use of Umbra, a product of Fizz Labs Co. ("we", "us"). By installing or subscribing, you agree to them.
What Umbra is
Umbra is an Android privacy app that disguises a second, fully separate phone behind a working calculator, unlocked by a secret code you choose. It uses Android's Device Owner and multi-user features and requires a one-time factory reset during setup.
Lawful use only
Umbra is intended to protect the privacy of your own device and data — for example when crossing a border, sharing a phone, or guarding against theft. You agree to use it lawfully and in accordance with the rules of your jurisdiction. You must not use it to hide unlawful activity, to deceive in violation of any law, or on a device you do not own or control. You are responsible for complying with local laws, which vary by country.
Device compatibility & the factory reset
Setup requires a factory reset so the app can become the device's manager. You must back up your data first. The app includes a compatibility check you should run before resetting — some devices (notably many Samsung consumer/carrier models) do not allow the multiple users Umbra needs and are not supported. We are not responsible for data lost by skipping the backup or compatibility steps.
Subscriptions & licences
Umbra is offered as a monthly or annual subscription after a 3-day free trial, or via a prepaid multi-month code. Subscriptions renew automatically until cancelled. Your licence is an anonymous code; keep it safe, as we have no account system to recover it from. Refunds are covered in our Refund Policy.
No warranty
Umbra is provided "as is". We work hard to make the concealment robust, but we cannot guarantee it defeats every possible inspection, forensic tool, or future OS change, and the second user may still be visible in some system screens (an inherent platform limitation we disclose openly). To the maximum extent permitted by law, we disclaim implied warranties and are not liable for indirect or consequential damages. Our total liability is limited to the amount you paid in the prior 12 months.
Changes
We may update these terms or the app. Material changes will be posted here. Questions: support@fizzlabs.ai.
