PearList

PearList collects no personal data. Your lists live on the phones of the people you share them with. Nothing readable is ever sent to a server. No account required.

All data is stored locally on the devices in your household group:

• Your lists and their items (names, checked state, quantities, notes)
• Who an item is assigned to, when you use a list as a chore board
• The display name you choose for yourself
• Pairing keys that identify the members of a household group to each other
• App preferences

None of this data leaves your devices except to sync directly between the members of your group (see Peer Sync below).

PearList syncs your lists directly between the devices in your household group using the Hypercore Protocol, a peer-to-peer technology. There is no server storing your data and no account. On networks where a direct connection cannot be made, the connection can fall back to the PeerLoom relay described below, which forwards the encrypted traffic without being able to read it. Data is shared only with the specific devices that have joined your group.

All sync traffic is encrypted end-to-end, and every change is cryptographically signed by the device that made it. No third party ever receives or has access to your household's lists.

Most of the time your devices connect to each other directly. On a small number of networks that direct connection cannot be made at all. In that case PearList can fall back to a relay that PeerLoom runs, which passes the encrypted traffic between the two devices.

The relay cannot read what passes through it. Your lists stay encrypted end to end and PeerLoom holds no key to them. What a relay unavoidably handles is the fact that two devices are talking, identified by random public keys rather than names or email addresses, along with the timing and the amount of data. The relay keeps no record of it and stores nothing.

The relay is a last resort and never the first choice. The relay can be turned off, in which case PearList is purely device to device and will not connect on the rare networks where a direct connection is impossible. Full detail: The PeerLoom relay.

• Camera: Used to scan the QR code when you join a household group. Nothing from the camera is stored or transmitted.
• Notifications: Used to deliver local alerts such as an item assigned to you or a new member joining. Notification data never leaves the device.
• Network and local network access: Used for peer-to-peer connections between the devices in your group, including directly over your Wi-Fi, and for the relay fallback described above. No readable data is sent to any server.

PearList contains no analytics, no advertising SDKs, no crash reporting services and no third-party trackers of any kind.

PearList does not require you to create an account or provide an email address. Each device's identity is a cryptographic key pair generated locally.

PearList is fully open source. You can inspect the complete source code at github.com/peerloomllc/pearlist.
