Your photos already know where you have been. Stourk reads only the date and place stored with them and turns the whole collection into a journey: a stork carrying your memories across an illustrated atlas, city by city, year by year. WATCH THE JOURNEY Choose a year, or your whole life, and watch the places become a route. The map is a printed atlas, not a satellite view; the route is drawn as the shortest arc between the places your photos know. Scrub through it, jump to a moment, and see the photographs from that stop as you pass. THE POST Every city you stayed in writes to you. Its letter is addressed by hand, stamped with the city's own postage, and postmarked by the Stourk postal service. Tear one open and the city's own note comes out first, then the photographs from that city. THE PASSPORT Every country you entered is stamped into a passport: rubber ink, struck askew, dated. Turn the pages. Tilt your iPhone and the pages keep a surprise for you. THE CASE Journeys earn luggage labels. They stick to a suitcase you keep. KEEPSAKES Save a journey as a poster or a short film, and share it. PRIVATE BY DESIGN Stourk has no account, no server and no analytics. It reads photo dates and locations on your iPhone, keeps what it builds there, and never uploads a photograph or a place. Your library is read-only to it. Clear the local data whenever you like; Stourk will not read your library again until you ask. The only network traffic is the map itself, vector tiles from OpenFreeMap with data from OpenStreetMap contributors, and, for a photo that lives only in iCloud, that photo from Apple. English and Turkish.
