Musafir — prayer-aware day planner for Korea · Effective 8 November 2026 · 한국어

Musafir is a free hobby project made by Park Soon-young (박순영). It has no accounts and no server of its own. This page says what the app keeps, what leaves your phone, and how to stop it.

1. Kept only on your phone

Your plan (city, date, stops, hotel), settings, saved places and prayer reminders are stored in the app on your phone (browser storage on the web). They are not sent to us and are not backed up to the cloud. Prayer times, qibla direction, routes and taxi estimates are worked out on the phone.

Your location is read only when you tap a button that uses it (for example "Use my location"). On Android the app asks only for approximate location. It is used on the phone to find nearby places and is not sent to us.

2. Online features (Kakao) — on by default, can be turned off

To show the Kakao map, search places and hotels by name and find halal food and prayer rooms nearby, the app talks directly to Kakao Corp. While these features are on, Kakao receives the map area you are looking at, the words you search for and the places in your plan; coordinates sent with searches are rounded to about 1 km. Turn this off in Settings → Privacy → Online features; the app then uses its own offline map and data. Kakao's handling is set out in Kakao's privacy policy.

3. Anonymous usage statistics (PostHog) — can be turned off

To see which features help travellers, the app sends usage events to PostHog Inc. (United States). Events say which screen or feature was used, for example: app opened, tab viewed, stop added (with the id of a place that ships with the app, or just "found by search"), hotel set (how: search, map or location — not where), search made (map or hotel, online or offline, number of results — not the words), compass started, taxi card or phrase card opened, directions opened, emergency number tapped (112, 119 or 1330), Friday prayer mosque added, reminders or online features switched, coffee purchase result.

Each event also carries the app language, chosen city, prayer calculation method, app version, platform (Android or web), device and browser type, and a random identifier stored on your phone so that repeat use can be counted. PostHog may estimate the country and city of the connection.

Never sent: your location or coordinates, your hotel name or address, words you search for, names of places you found online, anything you show on a phrase card, your name or contact details. IP addresses are not stored (the app sends with ip: false and the project discards client IP data). There is no session recording.

Statistics are kept for one year. Turn them off in Settings → Privacy → Anonymous usage stats; nothing is sent while it is off.

4. Coffee (tips) on Android

Buying a coffee is handled by Google Play. The app receives only whether the purchase went through, so it can thank you and let you buy again. We do not see your card or payment details. See Google's privacy policy. On the web, the coffee link opens Buy Me a Coffee, which has its own policy.

5. Feedback and place reports

If you send feedback or report a place, the form (or e-mail) includes what you write and, for a report, the public name and id of that place and the city. Only send what you are happy for us to read.

6. Sharing

We do not sell or share information with anyone else. The services above (Kakao, PostHog, Google Play) process it on our behalf or as part of the feature you use.

7. Children

The app is meant for travellers and is not aimed at children.

8. Your choices and contact

Turn off online features or statistics in Settings at any time; delete the app (or clear the site's data) to remove everything kept on your phone. Questions or requests: newmadlog@gmail.com (Park Soon-young).
