Lists first. Extras when you need them.

Installation is not available yet

The first candidate is 3.1.0 (30). There is no qualified new APK to install. Your inviter will provide the exact version, file hash and signing identity when it is ready. Android 9 or newer and a supported 64-bit device are required for the non-debuggable release.

Install only the file offered by your approved service. Review Android's installation prompt. Never uninstall or clear app storage to resolve an update failure: that can remove device-only lists, pending edits and receipt originals. Contact your inviter instead.

Find your way

Home contains lists and notebooks. Enter adds a grocery and keeps you ready for the next one. The menu opens Scan & receipt history, planning, price history and Account & settings. A notebook invitation grants its stated role; signing in alone does not join a household.

Save details distinguish edits stored on your device, edits waiting to synchronize and service acknowledgments. Open the app and reconnect to synchronize; there is no guaranteed background delivery.

Choose Light, Dark or OLED Black in Account & settings. Optional prices and planning are separate from adding a grocery.

Receipt backup and review

Private server backup is required before this initial release can be offered. New accounts will start with backup ON after disclosure. Existing accounts must review historical upload enrollment. You can opt out; research is separately OFF by default. Each image needs its own server acknowledgment.

Unreadable receipts still need an admission path; recognition success must not decide whether a valid receipt can be backed up. Non-receipt images must be rejected. Those protections are not yet qualified.

Recognition is a suggestion. Compare amounts and quantities with the original before confirming purchases. Deleting receipt evidence preserves confirmed purchase history. Evidence expires no later than three calendar months from original acquisition.

Updates

Your inviter announces reviewed app and server updates with release notes. Use the same verified signing identity and install the newer app over the existing one. Confirm your notebooks and pending edits afterward. If Android rejects the signer or version, keep the current app and contact your inviter. Experimental Scan and Fuel source will not update an installed beta automatically.

Candidate release notes

Source preparation includes lists, notebooks, invited accounts, sharing, offline edits, Product Memory, purchase history, inventory, recipes, meal plans, manual price comparison, trip planning and receipt review. Current-source runtime checks remain pending.

Product/barcode scanning and dedicated fuel history are deferred. Live retailer prices, live road routing, automatic purchases and research processing are unavailable. Qualified private receipt backup is a release blocker, not an optional exclusion.

Support will be provided through the inviter's approved contact method before anyone joins. Never include passwords, invitation links, recovery codes or receipt photos in a public issue.
