Privacy Policy
Last updated: November 11, 2026
General information
Hookcast (“we,” “us,” or “our”) is developed by Dmitrii Cherviakov and lets users create short video ads from a photo of a product or a screenshot of an app. This Privacy Policy explains how we collect, use and protect your data when you install and use the Hookcast mobile application (“App”) and visit this website. By accessing or using the App, you consent to the practices described here.
Information we collect
Hookcast collects the following types of data to deliver its services and improve the user experience:
- App identifiers: an anonymous identifier that distinguishes app installations, and an App Check token that confirms requests come from the genuine App. They do not reveal who you are.
- User-provided content: the photos and screenshots you choose, the ad scripts you type and the descriptions of custom AI actors. They are sent to our servers and processing partners to generate your ad. Your photos and finished ads are also stored on your device so you can reuse them. We also keep the photos you choose for generation on our servers (see Data retention).
- Crash and performance data: gathered automatically through third-party tools to diagnose and fix problems.
- Device information: device model, operating system and app version, used to optimize the App.
- Usage data: in-app events such as “ad generated” or “plan purchased”, used only for our internal analytics.
- Purchase information: subscription status and purchase history. Payments are processed by Apple; we never see your payment details.
- Push notification token: only if you allow notifications, so we can tell you when an ad is ready.
Important: you are responsible for making sure that any third-party personal data you upload, including photos of other people, complies with applicable privacy laws.
How we use your data
- Core functionality: writing the ad script, composing the first frame and generating the video from your photo.
- Subscriptions: providing paid plans and keeping track of the number of ads included in them.
- Performance optimization: monitoring crash reports and usage trends to improve stability and the user experience.
- Service communication: push notifications when your ad is ready or fails (you can turn them off in iOS Settings).
- Security: preventing abuse of the service and violations of our Terms and Conditions, and protecting it from fraudulent requests. For this, we keep the photos used for generation and a record of the requests our content checks refuse.
- Support and troubleshooting: answering your questions and solving technical issues.
We do not sell your personal data and we do not use your photos to train AI models ourselves.
Data sharing and storage
Hookcast works with trusted third-party services. Each processes data only for the purposes below and under its own privacy terms:
- OpenAI (OpenAI, L.L.C., USA): analyzes your photo, writes the ad script and composes images. Under OpenAI’s API data policy, data sent through its API is not used to train its models, and OpenAI may keep it for up to 30 days to monitor abuse before deleting it.
- MiniMax / Hailuo AI: renders the video from the first frame and script.
- Google Firebase (Google LLC, 1600 Amphitheatre Parkway, Mountain View, CA 94043, USA): internal analytics (how the App is used), crash diagnostics, remote configuration, App Check and push notifications. We do not use this data for advertising.
- RevenueCat (RevenueCat, Inc., USA): manages subscriptions and in-app purchases.
- TikTok and Instagram: only when you choose to share an ad to them from the App.
- Hosting providers: run the servers that pass your requests to the services above.
Some of these providers are located outside your country, including in the United States. Where required, transfers are protected by appropriate safeguards such as the EU-U.S. Data Privacy Framework or Standard Contractual Clauses.
Data retention
Your data is kept only as long as necessary to fulfill its purpose or to comply with legal obligations. The photos you choose to generate an ad from, including those our content checks refuse, are kept on our servers to protect the service against abuse, linked to the App’s anonymous identifier, accessible only to us, and deleted automatically after 30 days. To generate your ad, the photos are passed to the services above, and the result is returned to the App. The AI providers may keep this data for a limited time under their own policies, as described above. Photos and ads in the App are stored on your device until you delete them or remove the App.
Data security
We implement technical and organizational measures to protect your data against unauthorized access, loss or misuse, including encrypted connections and verification that requests come from the genuine App.
Your rights
The App has no user accounts. We do not ask for your name or email address, and the data we hold is linked only to an anonymous identifier created when you install the App. You can:
- Delete data on your device: delete photos and ads in the App at any time. Deleting the App removes everything it stored on your device.
- Control permissions: turn off photo access and push notifications at any time in your iPhone’s Settings.
- Ask about or delete your data: contact us at support@hookcast.org to ask what data we hold about you or to have it deleted from our servers. Because we have no accounts, we may ask for details that help us find your data, such as when you used the App.
Depending on where you live, you may have other rights under local law. Contact us and we will respond as that law requires.
Children
Hookcast is not intended for children under 13, and we do not knowingly collect their data.
This website
This website does not set cookies and does not use analytics. Fonts are loaded from Google Fonts. Links to the App Store may carry a campaign tag so we can tell which page led to a download.
Before the App is released, you can leave your email on this website to be told when it is out. We use it only to send you that message, store it on our own server and do not share it with anyone. You can ask us to delete it at any time.
Updates to this Privacy Policy
We may update this Privacy Policy to reflect changes in our practices or regulations. Significant updates will be announced in the App. Continued use of the App means you accept the updated policy.
