A lost-pet app could publish a controlled notice and let people send possible sightings through the platform. Owners should be able to receive information without putting a personal telephone number or home address on a public map.
Sightings need a time, approximate location and clear distinction between verified information and an unconfirmed report. Moderation, reporting and account controls can help limit misuse. Once an animal is found, notices should be closed or updated promptly.
Start with a local reporting workflow and test duplicate sightings and misleading submissions. Be cautious about displaying precise private locations. The app can organise a search and communication, but it should not promise recovery or present every submitted sighting as a reliable identification.
