❓ Frequently Asked Questions

---

What is OpenSAK?
OpenSAK is a free, open-source geocache management tool — a modern,
cross-platform successor to GSAK. It runs on Windows, Linux and macOS.

---

Is OpenSAK free?
Yes, completely free and open-source under the MIT licence.
Source code: https://github.com/AgreeDK/OpenSAK

---

What is the difference between OpenSAK and GSAK?
GSAK is Windows-only and now freeware but no longer actively developed.
OpenSAK runs on Windows, Linux and macOS, is actively developed, and is
fully open-source.

---

What file types can I import?

• GPX files from geocaching.com
• Pocket Query ZIP files
• Adventure Lab caches (LC prefix)

---

Does OpenSAK work without an internet connection?
Yes — once your caches are imported into the local database, OpenSAK works
fully offline. The map uses OpenStreetMap tiles which require internet, but
cache data, filters and logs work offline.

---

Does OpenSAK support Favorite Points?
Favorite Points are not available via GPX export from geocaching.com, so
OpenSAK cannot currently import them. This is a geocaching.com API
limitation, not an OpenSAK limitation.

---

Which languages does OpenSAK support?
Currently: English, Danish, Dutch, French, German, Portuguese, Czech and Swedish.

reproduce the issue.

---

Where do I suggest new features?

How do I stay updated on new releases?
New versions are announced in Announcements.
OpenSAK also notifies you automatically at startup when a new version is available.
