Effective date: 10 September 2026
These terms are the agreement between you and Estanislao Fusion for the use of Hookshift. Please read them. The sections on platform dependency (7), results (8) and liability (14) are the ones that most affect what you can expect.
Estanislao Fusion, Gustav-Gull-Platz 4, 8004 Zurich, Switzerland, referred to here as "Hookshift", "we" or "us". You are "you".
Payments are handled by Polar, which acts as merchant of record. That means Polar is the seller for your purchase and issues your invoice. These terms still govern how the service itself works.
Hookshift is a creative variant testing tool for short video. You upload video and supply hook text. Hookshift renders variants of that video across text, typeface and framing, and, if you choose, publishes those variants to your own Instagram account as trial reels on a schedule you set, then reports how each variant performed.
The purpose of the service is to find out which creative version of an idea performs best, before committing to it.
You must be at least 18 and able to enter a contract. You must give accurate account information and keep it current. You are responsible for what happens under your account, and for keeping your login credentials to yourself.
A subscription covers one Instagram account. Do not use one subscription to operate accounts belonging to different people or businesses.
To publish on your behalf, Hookshift needs you to connect an Instagram professional account and grant permissions. You can revoke that access at any time, from Hookshift's settings page or from Instagram itself.
You confirm that you own or are authorised to manage the Instagram account you connect. If you manage it for a client, you confirm the client has authorised this use.
Your use of Instagram remains subject to Instagram's own terms. Hookshift publishes only what you instruct it to publish, to your own account, at a pace you control. You remain responsible for the content you publish and for keeping your use within Instagram's Terms of Use and Community Guidelines. Hookshift's default limits exist to keep normal use well inside those rules, and you should not press us to raise them beyond what Instagram permits.
Everything you upload stays yours. You grant Hookshift a limited, non-exclusive, worldwide, royalty-free licence to store, process, encode, modify and display that content strictly for the purpose of operating the service for you: rendering variants, publishing them to your account at your instruction, and showing them back to you in the app. The licence lasts as long as we hold your content and ends when it is deleted.
We do not use your content to promote Hookshift, and we do not show it to anyone else without asking you first.
You warrant that you hold every right needed for the content you upload, including rights to any music, footage, images, text and any person appearing in it. Music is the usual trap: audio you bake into an upload must be audio you are licensed to use commercially. Hookshift does not supply, clear or licence music.
The Acceptable Use Policy is part of these terms. Breaking it is breaking this agreement.
Hookshift depends on Instagram's API, which is controlled by Meta and can change or be withdrawn at any time, with or without notice, and for reasons that have nothing to do with either of us.
If Meta changes, restricts, suspends or removes the access Hookshift relies on, and that reduces or stops the service, this is not a breach of these terms, and it does not give rise to damages. What it does give rise to: if the service is substantially unavailable for more than 14 consecutive days for this reason, you may cancel immediately and receive a pro rata refund of the unused part of your current billing period.
Hookshift is not affiliated with, endorsed by or sponsored by Meta Platforms, Inc. Instagram is a trademark of Meta Platforms, Inc.
Hookshift does not promise any particular number of views, reach, followers, engagement, sales, or any other outcome. What performs is decided by Instagram's systems and by your audience, and neither is under our control. The service tells you what happened; it does not decide what will happen.
The metrics shown come from Instagram and are reported as received. Instagram's own figures are estimates and can be restated.
Prices, plans and any free trial are as shown on hookshift.co at the time you subscribe. Subscriptions renew automatically at the end of each period until you cancel.
You can cancel at any time, effective at the end of the current period. Your access continues until then. We do not prorate refunds for a period you have started, except in section 7 or where the law requires it.
Prices can change with at least 30 days notice by email. A price change takes effect at your next renewal, and you can cancel before it if you would rather not.
If you are a consumer in the EU or UK, you have a statutory right to withdraw from a distance contract within 14 days. By starting to use the service during that period you ask us to begin performance immediately and acknowledge that you lose the right of withdrawal once the service has been fully performed. Nothing in these terms removes mandatory consumer rights you have where you live.
If you were given free or discounted access as a beta user, it lasts for the period we tell you and can be ended with 14 days notice. Beta features may be incomplete and may change or disappear.
You can delete your account at any time from the settings page.
We can suspend or terminate your account if you break these terms or the Acceptable Use Policy, if your payment fails and stays unpaid after notice, if we are required to by law or by Meta, or if your use puts the service or other customers at risk. Except where the breach is serious or where the law or Meta requires immediate action, we will tell you what the problem is and give you a reasonable chance to fix it.
If we terminate your account without cause, we refund the unused part of your current period.
On termination, your data is handled as set out in the Privacy Policy and the Data Deletion Instructions. Export your data before you delete your account.
We may change the service as it develops. If we remove a feature you rely on, or change these terms in a way that materially disadvantages you, we will give you at least 30 days notice by email, and you may cancel before the change takes effect and receive a pro rata refund.
The service is provided as it is. To the extent the law allows, we exclude implied warranties of merchantability, fitness for a particular purpose and non-infringement. We do not warrant that the service will be uninterrupted or error free.
To the extent the law allows, and except as stated in the next paragraph, our total liability to you for all claims arising out of or relating to these terms or the service is limited to the fees you paid us in the 12 months before the event giving rise to the claim.
We are not liable for indirect or consequential loss, lost profits, lost revenue, lost business opportunity, or loss of data, except where that data loss results from our failure to keep the backups described in the Privacy Policy.
Nothing in these terms limits liability for death or personal injury, for fraud, for intentional wrongdoing or gross negligence, or for anything else that cannot be limited under Swiss law or under the mandatory consumer law of your country of residence.
You will indemnify us against third-party claims arising from content you uploaded or published through the service, from your breach of these terms or the Acceptable Use Policy, or from your infringement of someone else's rights. We will tell you promptly about any such claim and let you control the defence, provided any settlement that imposes an obligation on us needs our agreement.
Swiss law governs these terms, excluding its conflict of law rules and the UN Convention on Contracts for the International Sale of Goods. The courts of Zurich, Switzerland have exclusive jurisdiction.
If you are a consumer, this does not deprive you of the protection of the mandatory law of the country where you live, or of your right to bring proceedings there.
If a provision is unenforceable, the rest stays in force. Not enforcing a right is not waiving it. You may not transfer this agreement without our consent; we may transfer it as part of a merger, acquisition or sale of the business, on notice to you. These terms, together with the Acceptable Use Policy, the Privacy Policy and the DMCA Policy, are the whole agreement between us about the service.
