Quick answers before you get lost in the map.

The usual reasons are being outside the allowed radius, having weak GPS accuracy, using an expired or already used QR, or trying to claim an inactive stamp. The goal is to keep normal claims easy while blocking fake ones.

A route is a curated journey made of ordered stamps. Published routes are locked snapshots, so they do not silently change under collectors. Your progress comes from the stamps you have already claimed, and route navigation keeps the intended order while skipping what you already collected when possible.

Stampoo can open directions in Apple Maps or Google Maps. If you have not chosen a default yet, the app will ask when you start directions from a stamp or route, and you can save that choice for next time. You can always change it later in Settings. Apple Maps is the native iOS option, but it can have trouble preserving every stop in routes with multiple stamps; Google Maps is usually more reliable for full multi-stop routes.

Creator Free is meant to let you operate with a real but limited footprint. Right now the product limits are up to 6 active stamps, 3 published routes, 2 active venues, and 1 active creator-carried mobile QR special stamp. Drafts do not consume quota.

Venue roles split operations from management. The owner is the top role and must always exist. Owners and managers can invite people, approve requests, change roles, remove members, and control venue stamp settings. Staff can run venue operations and generate allowed QR flows, but they do not manage permissions.

Stamp artwork should feel like a designed collectible, not a random camera-roll upload. Creators should upload square artwork only, with at least 800 x 800 px and ideally 1200 x 1200 px or more. The visible artwork window is centered inside the final framed stamp, and the key rule is to keep text, logos, faces and important details inside the safe zone. Accepted formats are PNG, JPG, JPEG, HEIC and HEIF. The app is responsible for generating the final framed composition, and the creator flow should expose the official guideline PDF so artwork can be prepared correctly.

A venue can have multiple active stamps, but only one primary stamp at a time. That primary stamp is the public face of the venue, the one shown on venue detail, and the one used when a route selects the venue directly instead of a specific special stamp.

A claim memory is a private keepsake linked to a stamp claim you personally earned. In V1 it is optional, camera-first, and private to you. A claim can only have one saved memory at a time, but if you delete it later you can create a new one.

Your past claim stays valid. Old claims do not disappear just because a stamp becomes inactive later, and published route versions remain historically true. If a route changes, the creator should publish a new version instead of mutating the old one under your feet.

Deleting your account permanently removes your access to Stampoo. Your public profile is anonymized, personal profile details are cleared, and your push tokens are deactivated. Stamps and routes you created may be archived so past collector history stays consistent.
