Terms of use
Last updated 15 September 2026
1. What this covers
These terms cover the LeaveSafe application and the account service behind it, both operated by SoftBlock Solutions Ltd, company number 16526424, registered in England and Wales, with its registered office at Suite 9331, 5 Brayford Square, London, E1 0SG, United Kingdom. Using either means agreeing to them. If you do not, do not use them — the open-source daemon below works without either.
2. The open-source part
The LeaveSafe daemon — the program that reads the sensors on your machine — is published under the Apache License 2.0 and is free. Nothing in these terms takes away a right that licence grants you, and nothing here applies when you run the daemon without an account. The paid tier described on this site does not close any part of it.
3. An account
An account is a sixteen-digit key. There is no e-mail address, no password and no recovery: if you lose the key, the account is gone and we cannot return it to you. That is a property of the design rather than a policy — we hold a hash of the key, not the key — and it is the price of an account that carries no identity.
Keep the key to yourself. Anyone holding it is, as far as the service can tell, you.
4. What you may not do
- Attack the service, or try to reach an account that is not yours.
- Work around the rate limits, or automate registration.
- Use LeaveSafe to watch a machine you have no right to watch, or a person. It is a device monitor, and using it to observe somebody without their knowledge is both outside these terms and likely outside the law where you are.
- Resell the service, or present it as your own.
5. Paying for an account
Time, not a subscription. An account is paid until an instant, and what is sold is a pack of days added to it — thirty, ninety or three hundred and sixty-five. Nothing renews itself, no card is stored and there is nothing to cancel: you stop adding time. Buying a pack while an account still has time extends it; buying one for an account that has lapsed starts from the moment of purchase, so no day is paid for twice.
The price is the store's. Packs are bought through the store the phone came with — Google Play on Android, the App Store on an iPhone — which shows the price in your own currency and collects the payment. No price is quoted on this site, because the store is the one that sets it and a second number here would be wrong the first time either changes.
Refunds follow the store's policy, and are asked for from the store rather than from us: from Google for a pack bought on Google Play, and from Apple for one bought on the App Store, at reportaproblem.apple.com, where Apple's own terms govern the purchase. When a store takes a purchase back — a refund, a chargeback or a reversal of its own — the days it bought are removed from the account, automatically and usually within hours. Time bought with other packs is not touched.
6. No warranty
LeaveSafe is offered as it is, without warranty of any kind. Understand what it is: a monitor, not a guarantee. It can tell you that something changed. It cannot stop anyone from taking your machine, it depends on sensors your operating system may not expose, on a network that may drop, and on a phone that may be asleep — and the free version cannot reach you at all once you leave the network. Do not rely on it as your only protection for anything you cannot afford to lose.
7. Liability
To the fullest extent the law allows, SoftBlock Solutions Ltd is not liable for indirect or consequential loss, for lost data, or for a device that was taken while LeaveSafe was or was not running. Nothing here limits liability that cannot lawfully be limited.
8. Changes, and ending it
These terms may change; the date at the top says when they last did, and continuing to use the service after a change means accepting it. You may stop at any time by deleting your account — see deleting your account. We may end an account that is being used to attack the service, and will say why where we can.
9. Governing law
These terms are governed by the law of England and Wales, and its courts have jurisdiction. If you are a consumer, this does not take away the protection of the mandatory law of the country you live in, nor any right you have to bring a claim there.
