This Privacy Policy explains how Ellington Electric (“Mindstir”, “we”, “us”) collects, uses and shares information when you use the Mindstir mobile app and related services (the “Service”). If you have questions, contact us at mindstir@ellingtonelectric.com.
1. Information We Collect
Information you give us
- Account information: your name, email address and password (we store only a secure hash of it, never the password itself). You may also add a profile picture, a short bio and a phone number.
- Onboarding preferences: your reasons for joining, interests, learning preferences and how often you’d like insights. We use these to personalise recommendations.
- Reading activity: books you save to your library, reading and listening progress, notes, highlights, bookmarks and reading streaks.
- AI chat: the questions you ask the in-app AI assistant about a book, and its answers.
- Books you upload: if you upload your own document (for example a PDF), we store the file and process its text to produce summaries and other learning materials for you.
- Community content: if you take part in the community, we store the posts and comments you publish, your reactions, saved posts, who you follow, who you block and any reports you file.
- Support messages: anything you send us when you contact support.
Information collected automatically
- Device and notification data: if you allow notifications, a push notification token for your device, plus basic device information needed to deliver them.
- Usage data: when you were last active, so we can keep track of streaks and send reminders you’ve turned on.
- Subscription status: if you subscribe, we receive your subscription status, product and expiry date from our subscription provider. We never receive your card or payment details. Apple or Google handles payment.
We do not use advertising SDKs, we do not show ads, and we do not track you across other companies’ apps or websites.
2. Using Mindstir Without an Account
You can browse the Mindstir catalogue without creating an account. In guest mode we don’t create a profile for you, and we don’t store any reading activity against your identity.
3. How We Use Your Information
- To provide the Service, including summaries, audio, flash cards, AI chat and your library
- To sync your progress, notes and highlights across your devices
- To personalise book recommendations
- To send the notifications you’ve opted into, such as reading reminders and community activity
- To manage subscriptions and give you access to premium features
- To run and moderate the community, and to keep it safe
- To respond to support requests, and to maintain, secure and improve the Service
4. What Other Users Can See
Your notes, highlights, library and reading activity are private by default. Other users see only:
- content you choose to publish in the community (posts, comments and highlights or notes you choose to share as a post), shown under the public name you confirm before posting;
- your profile picture, bio and the people you follow;
- your reading shelves, but only if you turn on “Show my reading on my profile”.
Your email address is never shown to other users. When you share a highlight or note, it is published as a separate copy. Your private original stays private.
5. How We Share Information
We do not sell or rent your personal information. We share it only with service providers that help us run Mindstir, and only as much as each one needs to do its job:
- Cloud hosting and database providers store and serve your account and app data.
- Cloudinary stores files such as profile pictures and documents you upload.
- OpenAI processes AI chat questions, and the text of books you upload, to generate answers, summaries and search indexes.
- Qdrant stores search indexes of book text so that AI answers can be grounded in the book.
- ElevenLabs converts summary text into audio narration.
- RevenueCat, together with Apple and Google, manages in-app subscriptions.
- Expo delivers push notifications to your device.
We may also disclose information when the law requires it, to protect the rights, safety or property of Mindstir, our users or others, or as part of a merger, acquisition or sale of assets. If that happens, this policy will continue to apply to your information.
6. Data Retention and Deletion
We keep your information for as long as your account is active. You can delete your account from within the app or by emailing us. When you delete your account, we permanently delete your profile, notes, highlights, bookmarks, library, reading history, AI chat history, uploaded books and community posts and comments. This cannot be undone.
Some limited records may remain after deletion:
- If one of your comments has replies, it stays in the thread as a “deleted” placeholder with its content removed.
- Moderation records, such as reports about content that broke our guidelines, may be kept to protect the community and meet legal obligations.
- Information in backups may last for a limited time before it is overwritten.
7. Your Choices and Rights
- Notifications: turn reminders and community notifications on or off in the app, or turn off notifications in your device settings.
- Profile visibility: choose whether your reading shelves are shown and whether others can discover you to follow.
- Blocking and reporting: block any user or report content from inside the app.
- Access, correction and deletion: you can edit most of your information in the app. To get a copy of your data, or to ask us to correct or delete it, email mindstir@ellingtonelectric.com.
Depending on where you live, you may have further rights under laws such as the Nigeria Data Protection Act 2023, the EU and UK GDPR, or California privacy law. These may include the right to access, correct, delete or port your data, to object to or restrict certain processing, and to withdraw consent. You may also complain to your local data protection authority, which in Nigeria is the Nigeria Data Protection Commission. We will respond to verified requests within the time required by law. We do not sell or “share” personal information for cross-context behavioural advertising.
8. Legal Bases for Processing
We process your information to perform our contract with you (to provide the Service). We also process it based on our legitimate interests in securing, moderating and improving the Service, and on your consent, for example for push notifications. Where processing relies on consent, you can withdraw it at any time.
9. International Transfers
We are based in Nigeria, and our service providers may process your information in other countries, including the United States. Where required, we rely on appropriate safeguards for these transfers, such as Standard Contractual Clauses.
10. Security
We use reasonable technical and organisational measures to protect your information. These include encrypted connections (HTTPS), hashed passwords and access controls. No system is completely secure, so we cannot guarantee absolute security.
11. Children’s Privacy
Mindstir is not directed at children under 13, and we do not knowingly collect personal information from them. If you believe a child under 13 has given us personal information, contact us and we will delete it.
12. Changes to This Policy
We may update this policy from time to time. If we make material changes, we will notify you in the app or by email before they take effect, and we will update the “Last updated” date above.
