Privacy Policy
Last updated: June 27, 2026
Markos Study is an AI-guided family Bible study app. A parent describes what their family needs, and we build and help lead a trustworthy, age-appropriate study. This policy explains what information we collect, how we use it, and the choices you have. It applies to our website, web app, and mobile apps (together, the "Service").
We built Markos Study around a simple principle: collect as little as possible, especially about children, and never sell or trade your family's information.
The short version
- A parent or guardian holds the account. Children do not have their own accounts and do not sign in.
- For each child, we keep only an optional nickname, an age range, and a reading level — never a full name, birthdate, photo, voice, contact details, or location.
- We do not show ads, we do not track you across other apps or websites, and we do not sell or rent your information.
- You can view, edit, export, or delete your family's information at any time, and you can delete your account and everything in it from inside the app.
Information we collect
We collect only what we need to provide the Service:
- Account information: the email address you use to create and sign in to your parent account.
- Family profile: a family name you choose, and your study preferences (such as preferred Bible translation, typical session length, and the kinds of activities your family enjoys).
- Children in your family: for each child you add, only an optional nickname, an age range, and a reading level — entered by you, the parent. This helps us pitch questions and activities at the right level.
- Study content: the requests you write, the studies we generate for you, your saved progress, memory-verse tracking, and any concerns you report to us.
- Operational data: limited technical and usage information needed to run and protect the Service, including how much AI processing a study used (so we can manage cost and reliability) and standard security and error information.
Information we do not collect
We do not ask for or collect a child's full name, birthdate, exact age, photograph, voice recording, email, phone number, school, or precise location. We do not build advertising profiles, and we do not use tracking technologies to follow you across other apps or websites.
How we use information
- To create, check, and deliver your family's Bible studies and answers.
- To save your progress so you can pause and resume across your devices.
- To keep the Service safe and accurate, including reviewing reported concerns and enforcing our safety and Scripture-integrity checks.
- To provide support and send you essential account messages.
- To understand overall, aggregated usage so we can improve the Service. We do not use this to track individuals across other services.
Children's privacy
Markos Study is designed to be operated by a parent or guardian on behalf of their family. Children do not create accounts, do not sign in, and do not chat directly with AI in private — a parent leads each study.
We practice data minimization for children by design: the only child-related information in the Service is the optional nickname, age range, and reading level that a parent chooses to enter. We do not knowingly collect personal information directly from children, and we do not serve behavioral advertising to anyone.
Parents are always in control. You can review, change, or delete your children's profiles and any saved responses at any time, and deleting your account removes them entirely. If you believe a child has provided us information without your involvement, contact us and we will delete it.
AI processing
To generate and verify studies and answers, we send the necessary content (such as your request and the relevant Scripture references and settings) to our AI providers. We use AI providers under business terms that do not permit them to use your family's content to train their models, and we send only what is needed to complete your request.
Generated content is checked against approved Scripture and reviewed for safety before it is shown. Scripture is authoritative; the AI is not. Generated explanations, questions, and activities are study aids, not a substitute for Scripture, your own judgment, or pastoral guidance.
How we share information
We do not sell or rent your information, and we do not share your family's study content for advertising. We share information only with service providers who help us run the Service, and only as needed for them to perform their work for us. These include providers for cloud hosting and our database, content delivery and security, and email delivery, as well as the AI providers described above. If we introduce paid plans, a payment processor will handle billing; we will not store full payment-card numbers.
We may also disclose information if required by law, or to protect the rights, safety, and security of our users, the public, or the Service.
Data retention and deletion
We keep your information while your account is active so the Service works as you expect. You can delete individual studies and responses at any time, and you can delete your entire account from inside the app — this removes your account, your family, and your studies and responses. You may also contact us to request access to, correction of, or deletion of your information.
Security
We protect your information with industry-standard measures, including encryption in transit and strict access controls so that each family's data is isolated and accessible only to that family's account. Human review is the final gate on study content. No method of transmission or storage is perfectly secure, but we work to protect your information and to limit what we collect in the first place.
Your choices
- View and edit your family profile, preferences, and children's information in Settings.
- Delete studies, responses, and your entire account from inside the app.
- Control whether responses are stored and use private sessions where available.
- Manage the essential emails you receive; we do not put sensitive family discussion content in email by default.
We send essential account and security messages, and study-related messages you ask for. Any optional updates are separate, and you can opt out at any time. We keep sensitive family content out of email by default.
Changes to this policy
We may update this policy as the Service evolves. When we make material changes, we will update the date above and, where appropriate, notify you. Your continued use of the Service after an update means you accept the revised policy.
