Safety First:Always Meet in Busy Public space

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.

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.

How Double Stop Works

SUPERMARKET

You're Already There

Whether you're at a café, public park, art gallery, dog park, library, airport, or before or while shopping at the supermarket—post a quick D-Stop. Share your activity and a friendly hint of where to find you. No accounts or photos are ever required. Your details stay locked and private until someone nearby is ready to meet, and every post automatically vanishes after one hour.

D-StopJohn?

You're in Control

Someone nearby discovers your post and chooses to unlock the details. They'll find you in person with a simple, friendly greeting: “D-Stop, [poster's name]?” It's a spontaneous, real-world connection designed for safety and privacy from the very first step.

Frequently Asked Questions

What exactly is Double Stop?

Double Stop (or D-Stop) is a location-sharing icebreaker app designed to turn idle waiting time into real-world, face-to-face connections. Whether you are standing outside a local supermarket, sitting in a cafe, or waiting for a delayed train, you can post a temporary 'wish' to chat about a shared interest. It helps you find people who are standing right in front of you and looking to have the exact same conversation.

Do I need to use my real name or upload a photo?

Absolutely not. Double Stop is built on privacy and anonymity. You do not use your real name or upload a profile picture. Instead, you pick a temporary nickname and write a brief note about your physical appearance in that exact moment—for example, 'I am wearing a blue jacket and yellow pants.' This protects your identity online while making it easy for a friendly stranger to find you in person.

How does the 1-hour self-destruct feature work?

We believe in leaving no digital footprint. Every post you make on Double Stop is completely ephemeral. Once you drop a pin on the map, a 60-minute countdown begins. After one hour—or the moment you manually close the session—your post is automatically removed from public view. We retain a secure, non-public archive for 90 days solely for legal compliance, after which it is permanently deleted.

Is Double Stop a dating app?

No, Double Stop is designed for true, platonic connections. We aren't trying to build a dating service; we want to foster local community. It is about finding a study buddy at the library, a fellow musician to talk shop with, or simply someone to chat with about daily meal ideas over a coffee. The focus is purely on shared interests and spontaneous neighborhood harmony.

How do I ensure my safety when meeting someone?

Because Double Stop is meant for immediate, local connections, you should always use the app in well-lit, public spaces with other people around—like cafes, shopping centers, or airports. You are always in control of your location sharing, and you can delete your pin instantly at any time. Furthermore, Double Stop is strictly for users aged 18 and older, and we actively moderate the platform to ensure a safe environment.

Is Double Stop available in my city?

Double Stop works anywhere in the world. There are no geographic restrictions — if you are in a city, a small town, or anywhere in between, you can post and discover posts near you. That said, the app works best in places with more foot traffic: busy city centres, university campuses, popular parks, and transport hubs. In quieter areas you may simply be an early adopter — someone has to be first.

What happens if someone doesn't show up?

That is always a possibility with spontaneous meetups, and it is completely okay. Their post may have already expired, or they may have simply changed their mind — which is entirely their right, and yours too. The key thing to remember is that Double Stop is designed around the idea that you are already there. You are already at the café, the park, the library. The connection is a welcome bonus, not the reason for the trip. If it does not happen, nothing is lost — you are exactly where you planned to be anyway.

Can I use Double Stop if I don't speak the local language?

Yes. You can write your post in any language you are comfortable with, and you can include the language you speak in your post details so others know what to expect. Double Stop is designed for travellers and expats as much as locals — a shared language of curiosity and openness goes a long way. The app interface itself is available in English, German, Spanish, French, Mandarin Chinese, Korean, Japanese, and Arabic.

What makes a good "strong opinion" to share?

The "strong opinion" field is your personal signal in the physical world. It is the personality hook of your post — it can be controversial — and it is the beacon that makes a stranger nearby stop and think, "I have to say hello to this person." We encourage you to be unfiltered. While it takes courage to be fully honest, sharing your true "Love/Hate" helps you be found by the people you actually want to meet. It ensures that when someone does find you, it is because they connected with the real you. For example: - "The best part of any trip is the aimless wandering, not the famous landmarks." - "I prefer a rainy day at home over a sunny day at the beach." - "Pineapple does not belong on pizza for my taste." - "Social media has made us more lonely, not more connected." - "Rewatching a favorite show for the tenth time is better than starting a new one." - "We should go back to using physical buttons in cars instead of touchscreens for everything." Keep it honest — the stranger reading it should immediately know whether they agree or disagree. That is the point.

How is Double Stop different from dating apps?

Double Stop is explicitly not a dating app. There are no profile photos, no swiping, no matching algorithm, and no private messaging. The app is designed for platonic, in-person connections — a study partner, a fellow traveller to share a coffee with, someone who wants to talk about the same book. Romance is not the goal, and the design reflects that: posts are anonymous, temporary, and focused on what you are doing right now, not on who you are trying to become.

Is Double Stop free to use?

Yes, completely free. Posting, browsing, and connecting on Double Stop costs nothing. The app is supported by advertising — a short rewarded ad plays when you choose to unlock the full details of a post. That is the only monetisation. There are no premium tiers, no subscriptions, and no paid features.

What happens to my post after 1 hour?

After one hour your post disappears from the public feed automatically and can no longer be found by other users. For legal compliance purposes, post data is retained in a private archive for 90 days before being permanently deleted. This archive is strictly for law enforcement cooperation if ever required — it is never visible to any user, including you. After 90 days, everything is gone permanently. Full details are in our Privacy Policy.

Can I edit or delete my post?

Yes to both. When you create a post you set a password. You can use that password at any time to edit the details of your post or delete it entirely before the hour is up. On the home feed, find your post and use the edit or delete options — you will be asked to confirm your password. Deleting a post removes it from the public feed immediately.

Is there a minimum age to use Double Stop?

Yes. Double Stop is strictly for adults aged 18 and over. By using the app you confirm that you meet this requirement. If you are under 18, please do not use the app. This is a firm rule, not a suggestion — the app is designed for adult spontaneous meetups and the risks involved require adult judgement.

What languages does Double Stop support?

The Double Stop interface is currently available in eight languages: Mandarin Chinese, English, Arabic, Spanish, French, German, Japanese, and Korean. You can switch languages at any time using the language switcher in the top navigation. Your language preference is saved locally so the app remembers it on your next visit. Post content can be written in any language you choose.

What order are the languages listed in the language switcher?

The languages in the switcher are ordered by the number of people who speak them worldwide — from the most widely spoken to the least. This means Mandarin Chinese and English appear near the top, while less globally widespread languages appear further down. Arabic has been added to reflect its status as one of the most spoken languages in the world.

Should I tell someone where I'm going before a meetup?

Yes, always. Before meeting anyone from Double Stop, let a trusted friend or family member know where you are going, who you are meeting (as much as you know), and when you expect to be back. This is good practice for any spontaneous meetup with a stranger. A quick message takes seconds and adds an important layer of personal safety. You can also check in with them once you have arrived and feel comfortable.

What should I do if I feel uncomfortable during a meetup?

Trust your instincts — always. If something feels off at any point, you are completely free to leave. You do not owe anyone an explanation. Move to a busier area, go inside a shop, or simply say you need to go. Do not feel obligated to stay in any situation that makes you uneasy. Your safety is the only thing that matters. If you feel you are in immediate danger, contact local emergency services straight away.

Can I report inappropriate posts?

Yes. If you see a post that violates our community guidelines — anything suggestive, threatening, designed to target a specific person, or otherwise inappropriate — please use the contact form on our homepage to report it. Include as much detail as you can. We take reports seriously and will act promptly. Posts that violate our Terms of Service will be removed and the responsible party may be permanently banned.

Does Double Stop track my location permanently?

No. Double Stop only uses your location for the duration of your post — a maximum of one hour. You choose your location manually by placing a pin on the map; the app does not use your device’s GPS or track you in the background at any time. Once your post expires, your location data is removed from the public feed. We do not build location profiles, sell location data, or share it with third parties. See our Privacy Policy for full details.
