Reserve is made by Marrow. Reserve is an iPhone app that helps you turn proven activity into minutes for apps you choose to hold back.
Reserve stores its ledger, settings, activity proofs, and Screen Time selections on your device. It has no account and no Marrow server that receives this data.
Apple gives Reserve opaque Screen Time tokens. Reserve cannot read the names, bundle identifiers, or categories of the apps you select.
Health access is optional. If you allow it, Reserve reads steps, workouts, and mindful minutes as activity proof. You can also choose to save guided-breathing sessions to Apple Health. Reserve does not send Health values to Marrow.
You can connect your own Burgeon instance. If you do, Reserve reads only the data needed to check a reflection proof. It does not read reflection text. This connection goes directly between your device and the Burgeon address you configure. Marrow does not operate that service.
Reserve does not collect app names, reflection text, Health values, your device name, location, contacts, advertising identifiers, or crash reports. Reserve does not use advertising or third-party tracking SDKs.
Reserve does not currently send usage analytics. If a later beta build adds optional anonymous usage analytics, Reserve will update this policy before that build is released.
You can revoke Screen Time or Health access in iOS Settings. You can remove the Burgeon address in Reserve. Deleting Reserve removes its local data from the device, subject to normal iOS system behavior.
