Kidea (“we”, “our”, or “us”) is a learning app designed for children and young people. This Privacy Policy explains what information we collect, how we use it, and your rights, especially for users under 13. Please read it with your child or teen if they use the app.
Kidea is operated by Esa Tanskanen, located in Finland, who acts as the data controller for the personal data described in this policy. For contact details, see section 12 (Contact).
By using Kidea, you agree to this Privacy Policy.
Kidea is primarily intended for users aged approximately 7–18 years and their parents or teachers. We take privacy seriously and follow applicable laws, including the Children’s Online Privacy Protection Act (COPPA) in the United States and the General Data Protection Regulation (GDPR) in the European Union/EEA.
Kidea does not include sign-in or account creation. The app also does not include an age-gate flow. Profile names and grades are optional and are stored only on the device.
“Personal information” means information that identifies an individual or a device—for example, an account identifier, name, email address, or similar data.
The following information is stored only on your device and is not uploaded to our servers or shared with third parties:
When you use features that need our servers, we receive and store:
When you create or use study content (e.g. chapters, learning steps, songs, or adventures), we send to our servers the information needed to generate that content. When you create a chapter from photos of textbook or chapter pages, we send those images to our servers and to Google Cloud Vision for text extraction (OCR) only; the images are processed in memory and not stored by us or by Google for this purpose. For other study content we send only text and metadata—for example: chapter text, terms, definitions, bullet points, character descriptions, and language. This content is processed by our servers and by service providers (AI providers such as OpenAI for content generation and MusicGPT for music/song generation from lyrics, and cloud providers such as Google Cloud for infrastructure and services such as text-to-speech) to generate study materials, images, speech, or music. Content sent to our AI providers is used only to generate the requested study materials and is not used by us to train AI models, in line with our agreements with those providers. We do not store photos you send for this purpose; they are processed only to generate the requested materials.
If you choose to share a chapter, the app may upload a limited snapshot to our servers so we can give you a link for others to open in Kidea. That snapshot includes only transformed study aids from chapter creation—for example book and chapter names as labels, summary, key points and terms from the initial chapter bundle, and language—not full book text, photos, audio, your profile name, grades, or other personal results, and not separate “all terms” or “all bullets” expansions. We do not upload original source pages or copyrighted body text. We store that snapshot for approximately 30 days, after which it is deleted. Sharing is voluntary; recipients need the app to use the link as intended.
We use the information we collect to:
We do not use personal information for advertising directed to children beyond what is permitted under child-directed ad policies (e.g. contextual, non-personalized ads).

We do not sell personal information. Photos sent for OCR are processed in memory and are not stored by us or our service providers.
Kidea is designed to minimize personal-data collection for all users, including children under 13. We use technical identifiers only for internal operations such as security, fraud prevention, and service integrity. Kidea does not include sign-in, account creation, or an age-gate flow.
Users are not required to provide more personal information than is necessary. For example, a profile name and grade are optional and are stored only on the device.
You may:
To do any of this, please contact us using the details in section 12. We will respond within a reasonable time (e.g. as required by law, such as within 30 days under COPPA).
Depending on your location, you may have the right to:
In Finland, the supervisory authority is the Office of the Data Protection Ombudsman.
To exercise these rights, contact us using the details in section 12 (Contact).
We use reasonable technical and organizational measures to protect the information we process—for example, secure connections (HTTPS), access controls, and secure storage. No system is completely secure; we encourage you to use a secure device and to keep account and device access limited to trusted persons.
We may update this Privacy Policy from time to time. We will post the current version at https://www.dancingmanatee.com/restudy/privacy.html (and in the app where applicable). Where required by law, we will notify you of significant changes (e.g. in the app or by email). The “Last updated” date at the top shows when the policy was last revised.
