Privacy Policy

Effective October 24, 2026

1. Who we are

Explainer Engine (the "Service", "we", "us") is a service at explainerengine.me that turns study material into explainer videos. It is operated by its developer, an individual based in the State of Illinois, USA. Questions about this policy: use the contact form on our home page.

2. What we collect

• Account details: your e-mail address, the name and language you give us, and a record of your sign-ins. You sign in with a one-time link sent to your e-mail; we have no password of yours.
• What you give us to make videos: the study material you upload, your notes and requests for changes, and photos you choose to upload to create a presenter.
• What the Service makes for you: plans, scripts, storyboards, voice recordings, videos, captions and publication texts.
• Accounts you connect: if you connect a publishing account (such as YouTube, Instagram or TikTok), we store the access tokens that platform gives us, the channel or account identifier, and the status of each publication. If you link Telegram, we store your Telegram chat ID to send you notifications. If you give us an API key for a third-party service, we store it encrypted and use it only for your work.
• Messages to us: your name, e-mail address and message when you write to us.
• Technical logs: our servers record requests and errors, which can include your IP address, browser type and the time of a request. We use them to keep the Service working and secure.

We do not collect payment card or bank details, Social Security or other government identification numbers, precise location, or contacts.

3. Photos and biometric information

A photo you upload is used only to draw a stylized presenter for your videos. We do not use photos to identify anyone. We do not create, collect or store face templates, face-geometry measurements or any other biometric identifiers or biometric information, as those terms are used in the Illinois Biometric Information Privacy Act. Upload only photos of yourself, or of people who have agreed to it. You can ask us to delete a photo and the drawings made from it at any time.

4. How we use information

• to sign you in and keep your account and channels separate from other people's;
• to make your videos, and to publish them to your connected accounts only after you approve the release;
• to send you the notifications you set up, and to answer your messages;
• to keep the Service secure, find and fix problems, and prevent abuse;
• to comply with the law.

We do not sell or rent your personal information, and we do not share it for advertising.

5. AI processing and model training

To make your videos, we send your material, notes, photos and the texts made from them to third-party AI services. These services may keep that content and use it to train and improve their models, under their own terms. We do not control that use, and once content has been sent we cannot have it removed from a provider's systems or models.

Do not upload confidential information, trade secrets, or personal information about other people that you do not want used this way.

6. Who we share it with

Only with service providers that help us run the Service, and only what each needs for its task:

• hosting, database and sign-in providers;
• a cloud file storage provider, where your material and videos are kept;
• AI service providers that generate text, speech and images from the content of your task, and may use it to train their models (see section 5);
• network providers that carry traffic to our servers;
• Telegram, which carries notifications you set up and the messages you send us through the contact form;
• the publishing platforms you connect, which receive a video and its text only when you approve its release.

We may also disclose information when the law requires it, to protect the rights and safety of users or the public, or as part of a transfer of the Service, in which case this policy continues to apply to your information.

7. YouTube, Google and other platforms

The Service uses YouTube API Services to upload the videos you approve to your YouTube channel. By connecting YouTube you agree to the YouTube Terms of Service, and Google's handling of your data is described in the Google Privacy Policy. Our use and transfer of information received from Google APIs adheres to the Google API Services User Data Policy, including its Limited Use requirements.

You can remove our access at any time: for Google, in your Google account permissions; for Instagram, TikTok and Telegram, in that app's settings for connected apps. If you ask us to disconnect an account, we delete its tokens.

8. How long we keep it

• Account details, material and videos: while your account is active, and until you ask us to delete them.
• Messages to us: as long as needed to answer and follow up.
• Technical logs: only as long as needed for security and troubleshooting.

Videos already published to YouTube, Instagram or TikTok stay there until you remove them on that platform. Deleting your data from the Service does not remove them.

9. Your choices and rights

You can ask us to show you the personal information we hold about you, to correct it, to give you a copy of your material and videos, or to delete your account and everything in it. We honor these requests for everyone, wherever you live, and answer within 30 days.

To delete your data, send a request through the contact form with the e-mail address of your account and the words "Delete my data". We confirm the request with that address before deleting. We delete your account, material, photos, videos, connected account tokens and Telegram chat ID from our systems, and write back when it is done. Content already sent to AI service providers is outside our systems (see section 5).

10. Security

Connections to the Service are encrypted. Access tokens and API keys are encrypted at rest, and only the parts of the Service that need them can read them. Each person sees only their own channels. No system is perfectly secure; if a breach affects your personal information, we will notify you as the law requires.

11. Cookies and browser storage

We do not use advertising or analytics cookies. When you sign in, your browser keeps a session token so you stay signed in. You can remove it by signing out or clearing your browser data.

12. Children

The Service is for adults. It is not directed to children under 13, and we do not knowingly collect their personal information. If you believe a child has given us personal information, tell us through the contact form and we will delete it.

13. Where data is processed

We and our providers process data in the United States and in other countries where those providers operate.

14. Changes to this policy

If we change this policy, we will post the new version here with a new effective date. If a change materially affects how we use your information, we will tell you by e-mail before it takes effect.
