Local-only information

InvoBaseOS information is stored locally on each device and does not synchronize between iPhone and iPad. Twin Unified Studios LLC cannot remotely view, retrieve, or repair your local invoices, customer records, credentials, or application data.

Master Key and 10-attempt recovery policy

Your randomized InvoBaseOS Master Key uses the format INV-REC-XXXX-XXXX-XXXX-XXXX. Twin Unified Studios LLC cannot view, recreate, reset, verify, or recover your Master Key. Never include your Master Key in this form, an email, a screenshot, or a screen recording.

InvoBaseOS allows a maximum of 10 recovery attempts. After 10 unsuccessful attempts, recovery access and the locally stored content protected by it may be permanently lost. Support cannot reset the attempt counter, bypass the recovery policy, unlock the app, or restore inaccessible content.

Important: Keep your Master Key secure and enter it carefully. Fully deleting InvoBaseOS can also permanently remove its locally stored information. To the maximum extent permitted by law, Twin Unified Studios LLC is not liable for lost or inaccessible content resulting from a missing or incorrect Master Key, exhausted recovery attempts, application deletion, device loss, storage failure, or other loss of local access. Do not delete the app as a troubleshooting step unless you understand and accept that risk.
