Pick how long. Photograph the combination and upload it. You don't get that photo back until the timer runs out, and nothing in here will let you talk your way around it early.
Set a number of days and watch them go down. Or set a range, let the server roll somewhere inside it, and find out when you find out. A rolled number never appears on the page — you get days elapsed and that's it. Either way, you can hide the clock entirely.
A ceiling is a date you're guaranteed to be out by. A floor is a date nothing can get you out before. Everything that touches your clock gets clamped by both, including the parts you handed to somebody else.
Entirely optional. Cells add time, take time off, freeze the clock, or set you a dare. Allow one spin per interval, let them stack up while you're not looking, or leave it unlimited and live with that. On a hidden timer it tells you what landed, not how big it was.
Send someone a link and they can add time without making an account. You decide the most one person can add at once, and the most the link can ever add in total. Nothing on a share link shortens a lock or opens a combo.
You get a six-digit code. Photograph your device with the code in the shot, which is what proves the picture is from today and not from last Tuesday. Publish one and other members vote on whether it looks right.
Yours lives at /u/you from the day you sign up: time served, how many locks, what you're in now, your counters, your gallery. Four switches in Settings turn any of that off. Your combo, notes, devices and share links are never on it.
Give yourself a set number of openings and a window for each one. Starting one hands the combo back. Closing it means setting a new code and photographing that, so you're properly sealed again instead of just promising you are.
Edge, ruin, locked, unlocked. One tap, and every tap remembers which lock you were in at the time, so the stats can tell you what actually changed. Devices carry what you paid and work out their own cost per hour worn.
How the seal works
One exception, and I'd rather say it than let you assume otherwise: I can open any image stored here, including a combo that's still sealed to you. If I ever do, a reveal date gets stamped on that lock and it shows up on your own page.
Emergency release
It gets noted against that lock permanently, and that's the entire price. Nobody can take this away from you — not a share link, not a ceiling, not me. Pain, numbness, colour changes, swelling, or anything that just feels wrong: get out now, and see a doctor if it doesn't settle down. No timer is worth an injury.
Every time in here is UTC, and the countdown ticks in your browser. Add it to your home screen from the share menu and it behaves like a normal app.
There's a Discord too, if you'd rather not do this on your own. You can also wire your own server up to your lock from Settings once you're in.
