Terms of Service

Effective 27 July 2026

Guillotine is an on-device video editor. It runs on your device, edits files you already have, and does not require an account. These terms describe what you can expect from the software and what we expect from you.

1. Who these terms are between

These terms are an agreement between you and the Guillotine project maintainer (HereLiesAz, “we”, “us”). By installing or using Guillotine you accept them. If you do not accept them, do not use the software.

You must be old enough to form a binding contract where you live, and old enough to use the app store you obtained Guillotine from.

2. The software and its licence

Guillotine is free and open-source software licensed under the GNU Affero General Public License v3.0 (AGPL-3.0). That licence governs your rights to use, copy, modify and redistribute the source code, and it prevails over these terms wherever the two conflict on that subject.

These terms cover the things the AGPL does not: the hosted website, the extension store, any purchases, and the ordinary conduct expectations that come with a service.

Guillotine is distributed in two builds — one via Google Play (ad-supported) and one directly from GitHub Releases (no ads, self-updating). Both are the same application.

3. Your content is yours

You keep all rights to the video, audio, images, text and projects you create or import. We claim no licence over them, and we do not — and structurally cannot — collect them: editing happens on your device and there is no first-party server that receives your media. See the Privacy Policy for detail.

You are responsible for having the rights to whatever you edit. Do not use Guillotine to infringe someone else's copyright, trademark, privacy or publicity rights.

4. Optional cloud AI (bring your own key)

Guillotine works fully offline using on-device models. If you choose to configure a cloud AI provider, you supply your own API key, and requests go directly from your device to that provider — never through us.

• Your use of any provider is governed by that provider's terms and privacy policy, and you are responsible for any fees they charge you.
• We do not control, endorse or take responsibility for provider output, availability, pricing or data handling.
• You are responsible for keeping your API keys secure and for any use made of them.

AI output can be wrong, biased, or unsuitable for your purpose. Review it before you rely on or publish it. Where a provider requires you to disclose AI-generated or AI-modified media, that obligation is yours.

5. Extensions and the Azphalt Store

Guillotine can install extensions (effects, presets, models) that conform to the azphalt standard, including from the Azphalt Store.

• Extensions are third-party content. Except where we are identified as the publisher, we do not author, vet, endorse or warrant them.
• Each extension carries its own licence, which governs your use of it.
• The app verifies an extension's integrity and, where the package is signed, its publisher, before installing. That is a technical safeguard, not a guarantee of quality or safety.
• We may remove an extension from the store at any time, and installing one is at your own risk.

6. Purchases

Some features or extensions may be paid. Purchases made in the Google Play build are processed by Google Play, not by us; Google's terms and refund policy apply, and refund requests go to Google. Purchases of third-party extensions are transactions between you and that publisher.

The ad-supported build shows advertising served by third-party networks. We do not sell your media or project content to advertisers.

7. Sharing to other platforms

Guillotine can hand a finished video to another application — for example your device's share sheet, or a social platform's own composer. Once the file leaves Guillotine, that platform's terms govern what happens to it, including any music, effects or licensing that platform applies. You are responsible for complying with the rules of wherever you post.

8. Acceptable use

Do not use Guillotine to create or distribute material that is unlawful where you are; that sexualises minors; that is designed to defraud, harass, or impersonate someone; or that you do not have the rights to. Do not use it to circumvent technical protection measures on media you do not own.

Because Guillotine runs entirely on your device, we generally cannot detect or prevent misuse — which makes it your responsibility, not a policy we enforce for you.

9. The embedded tool server

Guillotine can expose an editing tool interface (MCP) so an AI assistant can drive the editor. It is access-controlled by a token generated on your device and is off unless you use it. If you enable the optional relay to reach it remotely, traffic is end-to-end encrypted with a key derived on your device. Exposing it is your choice; secure your token accordingly.

10. No warranty

Guillotine is provided “as is” and “as available”, without warranty of any kind, express or implied, including merchantability, fitness for a particular purpose, and non-infringement. We do not warrant that it will be uninterrupted, error-free, or that any edit, export or analysis will be accurate or preserved.

Keep your own backups. Video editing is destructive by nature and software has bugs; do not entrust irreplaceable footage to any single tool, including this one.

11. Limitation of liability

To the fullest extent permitted by law, we are not liable for any indirect, incidental, special, consequential or exemplary damages, or for lost profits, lost footage, or lost data, arising from your use of Guillotine — even if advised of the possibility.

Where liability cannot lawfully be excluded, it is limited to the greater of the amount you paid us for Guillotine in the twelve months before the claim, or US$50.

Some jurisdictions do not allow certain exclusions, so parts of this section may not apply to you. Nothing here limits liability for fraud, or for death or personal injury caused by negligence, where the law forbids that limitation.

12. Indemnity

You agree to indemnify and hold us harmless from claims arising out of content you create or distribute with Guillotine, or your breach of these terms or of applicable law.

13. Changes and termination

We may update these terms; the effective date above will change and material updates will be noted in the project's release notes. Continuing to use Guillotine after an update means you accept the revised terms.

You may stop using Guillotine at any time by uninstalling it. We may discontinue the software, the website, or the store at any time. Because the software runs locally and is open source, discontinuation does not remove the copy you already have.

14. Governing law

These terms are governed by the laws of the jurisdiction in which the maintainer resides, without regard to conflict-of-laws rules, and you and we submit to the courts of that jurisdiction — except where mandatory consumer-protection law in your country of residence gives you the right to bring proceedings locally, which it does not remove.
