Your logbook, kept honest.
A logbook is a record you may have to prove one day — for a licence, a rating, a currency check. It only matters if it can't be faked, can't be sold out from under you, and can't be lost. Here's how SkyLog holds up its end.
A logbook is a legal record.
A paper logbook works because tampering with it is obvious — a torn page, a different pen, a signature that doesn't match. A digital logbook has to earn that same trust, and most don't. SkyLog does it with a sealed sign-off chain: every coach signature is locked to the one before it, so a signed jump can't be quietly rewritten after the fact. Alter one and the chain visibly breaks.
Your jumps stay yours.
SkyLog is paid for by skydivers paying for SkyLog — not by advertising, and not by selling jump data. We never have, and the model is built so we never need to. Your logbook is encrypted, it lives on servers in the EU under GDPR, and it is yours to take or to erase at any time: export the whole thing, or close your account and have it deleted.
Recognised where it counts.
A digital logbook is only useful if your federation accepts it. Several national bodies recognise SkyLog as a valid digital logbook, and the sealed sign-off chain is the reason — it gives a federation the tamper-evidence a paper book always did. Check your own federation's current position before you rely on it.

SkyLog is not a safety device.
We record what happened. We don't replace your altimeter, your AAD, your rigger, your instructor, or your judgement in the door. SkyLog makes your history accurate and provable — staying current and staying alive is still entirely on you and the people you trust at the dropzone.
A record you can trust.
