Why Double Stop?
Double Stop is a social signal for the physical world. It fills a gap that every app has ignored: the space between being alone in public and being genuinely open to a conversation.
Whether you are sitting alone at a café, relaxing in a park, browsing an art gallery, waiting at a transit hub, or before or while shopping at the supermarket — you are already there. Double Stop lets you signal to the people around you that a friendly hello is welcome, without interrupting your day or giving up your privacy.
Transparency and safety are built into the design at every step. Your detailed location and appearance remain hidden until someone nearby actively chooses to engage. Every post carries a shared social protocol: if someone approaches you with ‘D-Stop, [your name]?’, both of you know precisely what is happening — a mutual, informed decision to say hello. Posts expire automatically after one hour and nothing persists. The system is designed from the ground up so that spontaneous connections happen on your terms.
How It Works, Step by Step
Step 1 — Post a Signal.
Write a short post: a name (any name you choose), what you are doing, roughly how long you have, and an optional "strong opinion" — something honest about yourself that acts as a personal beacon for the right person.
Step 2 — Stay Private by Default.
Your detailed location and appearance are hidden until someone nearby chooses to engage. You share nothing publicly that could be used to identify you before you are ready.
Step 3 — A Stranger Says Hello.
Someone nearby discovers your post and unlocks the details. They find you in person with the simplest possible greeting: “D-Stop, [your name]?” No chat window, no profile page — just a real-world hello.
Step 4 — The Post Expires.
After one hour, your post vanishes from the public feed automatically. There is nothing to delete. The connection either happened, or it did not — and either way, you were already exactly where you wanted to be.
Who is Ina Works?
Ina Works is an independent software studio founded in 2025 and based in Salzburg, Austria. Salzburg is a city known for its human scale, rich public life, and a culture that still values the accidental conversation — the chance meeting at a market stall, the shared glance at a concert, the stranger who becomes a regular at the same café. Double Stop was built in that spirit.
Every design decision is made by a single developer, shaped by Austrian law and European data protection standards. The studio has no investors, no growth targets, and no advertising partnerships that conflict with user privacy. The product is accountable to its users and to Austrian courts — and that is intentional.
Privacy by Design
Double Stop has no mandatory user accounts and no photo uploads. This is not a limitation — it is an architectural decision made to protect you from the moment you open the app.
Your identity on Double Stop is three things: a name you choose, a brief description of your appearance, and a pin you place on a map. Posts expire after one hour. A private archive is retained for 90 days solely for legal compliance under Austrian law, then permanently deleted. There is no profile page, no post history visible to others, and no data sold to third parties.
Built for Salzburg’s Human Scale
Double Stop did not emerge from a product sprint in a corporate office. It grew from a specific observation in a specific city: Salzburg, Austria — a city of around 150,000 people where you can walk from one end of the Altstadt to the other in under twenty minutes.
That scale is the entire point. In Salzburg, the same faces appear at the same cafés week after week. The university culture around Unipark Nonntal and the Mozarteum keeps the city intellectually alive year-round. The city’s concert and festival tradition draws visitors who are, by definition, already open to new experiences. The characteristic mix of students, long-term residents, and creative professionals creates exactly the kind of social density where Double Stop makes sense: people already sharing the same squares and coffee houses, but lacking a bridge between them.
Double Stop is built and maintained here, by a developer who lives and walks these streets. That is not a marketing detail — it is the source of the product’s instincts. The 1-hour post limit reflects knowing that a Salzburg café does not hold a table forever. The decision to use human-scale location hints rather than raw GPS coordinates reflects knowing that ‘the bench near the Pegasus Fountain in Mirabellgarten’ means more than decimal numbers. The legal framework is Austrian because that is where this studio is registered, where this developer is accountable, and where the courts that protect users are located.
