HAT is free, open-source software. The license that actually governs the code is the GNU Affero General Public License v3.0. It covers copying, modifying, and sharing, and it applies to you automatically. This document is not that license. It exists to state, in plain terms, the disclaimers and the few use rules that the license alone doesn’t cover.
If you only read two sections, make them No warranty and Liability. The rest is shorter than it looks.
HAT is built by one person, published under the handle andromedvn, and distributed at no charge. There is no company behind it. The developer never receives your data: the app declares no internet permission, so it cannot send anything anywhere. The full details are in the Privacy Policy.
Anything AGPL-3.0 permits. Install it on your own devices, track your own time, export your data, fork the code, build your own version. Two things sit outside the license:
HAT reconstructs your day from events recorded by Android’s UsageStatsManager. That data is good, but it is not a sworn witness:
HAT is distributed through GitHub Releases only. The source is public under the AGPL, so anyone may compile and redistribute the app, and the developer has no control over those copies. The developer assumes zero liability for any binary that did not come from the official GitHub Releases page: third-party APK sites, modified builds with added permissions or tracking SDKs, or anything using HAT’s name. To check an official copy, compare its SHA-256 hash against the one published in its release notes.
THE APPLICATION IS PROVIDED “AS IS” AND “AS AVAILABLE”, WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED, including merchantability, fitness for a particular purpose, non-infringement, accuracy, completeness, and data preservation. Some jurisdictions do not allow some of these exclusions; in that case they apply to the fullest extent your local law permits.
TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, THE DEVELOPER IS NOT LIABLE FOR ANY DIRECT, INDIRECT, INCIDENTAL, SPECIAL, OR CONSEQUENTIAL DAMAGES, including loss of data, lost profits, or device malfunction, arising from your use of the Application. Because HAT is distributed at no charge, the developer receives no consideration from you, and the developer’s maximum aggregate liability to you is $0.00 (zero) or the minimum amount required by mandatory applicable law in your jurisdiction, whichever is greater.
Everything HAT stores lives on your device and dies with it. The Master Vault export exists precisely because the developer cannot recover a lost database for you. Back up before you uninstall, factory-reset, or switch devices. Deleting something in HAT is permanent; there is no cloud copy.
If you support development through the Ko-fi link in the app, that is a voluntary gift. It is not payment and grants no additional rights. It gates nothing: HAT is not trialware, not freemium, and every feature, present and future, is available to everyone whether they contribute or not. Contributions are processed entirely by Ko-fi under its own terms; the developer sees a payment notification and nothing else, and no contribution can be linked to your HAT installation, your data, or your device.
HAT is under active development, and this document will change with it. The current version is always the one published in the repository. If you continue to use HAT after a change, the changed terms apply. You can stop at any time by uninstalling; the app is entirely offline and nothing of yours is kept anywhere else.

These terms select no governing law and no venue. AGPL-3.0 governs the software. Your local mandatory consumer-protection and data-protection rights apply to you wherever you live, and nothing here tries to take them away.
