- Doodo keeps what you learn with it — your boards, questions, quiz results and what it notices about how you learn — so it can teach you better next time.
- Doodo for Chrome reads a web page only when you ask about it. It never records your browsing history and never stores whole pages or screenshots.
- We don't sell your data, we don't show ads, and we don't use your data to train AI models.
- To answer you, your questions go to AI model providers and your voice to a speech provider. They are listed below.
- You can delete a board, anything Doodo learned about you, or your whole account at any time.
What we collect
Your account
You sign in through our sign-in provider, Clerk, which holds your email address and sign-in details. Doodo itself keeps your first name and an account ID — not your email.
Your profile and preferences
What you tell Doodo when you set up and later: your level (school, college, exam prep), goals, interests, how you like to learn (examples first, visuals, hints or full solutions), pace, when and how long you study, how confident you feel in each subject, and any rules you give Doodo (“always use cricket examples”).
Your lessons
The questions you ask (typed, or the text of what you said), what Doodo said and drew, your answers to check-in questions, your explanations in your own words, and your feedback. Images you put on a board are stored with that board, and each board keeps a small picture of itself for your Boards page.
What Doodo learns about you
From your lessons and quizzes, Doodo writes short notes about how you learn: what you understand well, where you get stuck, misconceptions and whether you've fixed them, examples that worked for you, your goals and exam dates. You can see these notes — and change or forget any of them — on the Memory page.
Exams, plans and quizzes
Exams you add (name, date, subjects and syllabus), the topic map built from them, your progress and review dates, revision plans, quiz questions, your answers, and the reason you give for a mistake (“careless slip”, “didn't know it”).
How you use Doodo
A few signals that help Doodo pace your lessons: when you pause, stop or re-ask, the feedback you give, and the time of day and time zone you study in. We don't use third-party analytics or advertising trackers.
Your voice and uploads
When you speak to Doodo, the recording is sent to our speech provider to turn it into text and is not stored — we keep only the text. A syllabus photo or PDF you upload is read to pull out its text and is not stored; the text is saved only if you save the exam.
Doodo for Chrome
Doodo for Chrome is a browser extension that brings Doodo to the web pages you study. It adds a few things to the above.
When it reads a page
Only when you ask about it:
- you select text and click Explain (or Why?, Example, Simpler, Ask), right-click → Explain with Doodo, or press its shortcut;
- you ask a question in the Doodo panel while the page is open;
- you circle something on the page to ask about it (“draw to ask”);
- you ask Doodo to explain the whole page.
It then reads the main text of the page — headings, paragraphs, lists, tables, code and formulas, plus the part you selected or circled — so it can explain it and mark the right words. It skips menus, ads, forms and input fields, and it never reads passwords or what you type into a page. It stays off on banking, payment, email, messaging, password-manager and government-ID sites.
What leaves your browser
With your question, Doodo sends the page's address and title and the relevant page text to our servers and the AI providers below, to write the lesson. When you circle something, Chrome takes a picture of the visible part of the tab; Doodo crops it, on your computer, to the area around what you circled, and only that crop is sent.
What we keep
The lesson, as on the website, plus the page's address, title, site name and icon, so you can find the lesson again. Your question may contain the text you selected (up to a few hundred characters), and the lesson contains the short quotes Doodo marked on the page. We do not keep whole pages, screenshots or crops, and we never record which pages you visit.
What stays on your computer
The extension stores a sign-in token for your browser, your name, a copy of your exam and topic list, and its settings (such as the sites where you asked the Explain button to stay quiet). Disconnecting the browser removes the token.
Permissions
- Read and change data on all websites (optional, asked for once): lets the Explain button appear when you select text, and lets Doodo read and mark the page you ask about. Without it, Doodo works on a tab only after you click its toolbar icon.
- Side panel, storage, scripting, context menus, active tab: to show Doodo beside the page, remember your settings, run on the tab you ask about, and add “Explain with Doodo” to the right-click menu.
Doodo for Chrome's use of information complies with the Chrome Web Store User Data Policy, including its Limited Use requirements: the data is used only to provide the teaching features you use, it is not sold, not used for advertising, and not used to decide creditworthiness or lending.
How we use it
- To teach you: write each lesson for your level, goals and history, pick examples that work for you, and revisit what you got wrong.
- To save your work: your boards, exams, progress and reviews, on the website and in the browser.
- To plan: topic maps, spaced reviews, revision plans and weekly digests.
- To keep Doodo working: preventing abuse, applying fair daily limits, and fixing problems.
We don't sell your data, show ads, or use your data to train AI models.
Who helps us run Doodo
These companies process data for us, only to provide Doodo:
| Provider | What for | What they receive |
|---|---|---|
| Clerk | Sign-in and accounts | Your email, name and sign-in details |
| MongoDB Atlas | Our database | Everything Doodo saves for you (above) |
| Vectorize (Hindsight) | Doodo's long-term memory of how you learn | Your profile, lesson questions and Doodo's answers, your own explanations, exams, quiz results and Doodo's notes about you |
| OpenRouter, and the AI model providers it routes to (such as Google, OpenAI and Anthropic) | Writing lessons, reading images and pages, building quizzes, topic maps and plans | Your question, recent lesson history, a picture of the board or the part of a page you circled, the page text you asked about, and a short summary of what Doodo knows about you |
| Sarvam AI | Voice | The text Doodo speaks, and recordings of your voice to turn into text |
| Vercel | Hosting the website and its servers | Every request to Doodo passes through it |
Some of these providers process data outside India, including in the United States. We may also disclose information if the law requires it, or to protect people's safety.
What you share
Weekly digest links. When you write a weekly digest and share its link, anyone with the link can see your first name, that week's numbers (sessions, quizzes, topics done), what improved, what you keep finding hard, and how someone can help. The links aren't listed on search engines. They stop working when you delete your account.
Study buddies. If you turn on study-buddy matching on the Memory page, other students who also turned it on can see your first name and the topics where one of you is strong and the other is still learning.
How long we keep it
For as long as you have an account, so Doodo can keep teaching you — unless you delete something sooner. Daily usage counters expire within a day, and records of Doodo's background memory jobs after 90 days. When you delete your account, your data is removed from our database and from Doodo's memory straight away; copies in our providers' routine backups expire on their own schedules.
Your choices
- See it: your boards are on Boards, and what Doodo learned about you is on Memory.
- Correct it: edit your profile and teaching rules, or change or forget anything on Memory.
- Delete it: delete any board, memory note, rule or exam. To delete everything, go to Settings → Your data → Delete my account.
- Disconnect a browser: in Settings, or from the Doodo panel.
Depending on where you live (for example under India's Digital Personal Data Protection Act, 2023, or the GDPR), you may also have the right to a copy of your data, to withdraw consent, to nominate someone to act for you, and to complain to a data-protection authority.
Children and students
Doodo is made for students, including school students. If you are under 18, please use Doodo with your parent's or guardian's permission. Parents and guardians can delete their child's account at any time from Settings. Doodo doesn't show ads or track children for advertising.
Security
Data travels encrypted (HTTPS) and is stored by a database provider that encrypts it at rest. Browser sign-in tokens are stored only in scrambled (hashed) form and can be revoked at any time. Text from web pages is treated as material to teach from, never as instructions: Doodo for Chrome never clicks, types, submits forms or navigates on a page. No system is perfectly secure, but we work to protect your data.
Cookies and storage
The only cookies are the ones that keep you signed in (from Clerk). Doodo also stores a few settings in your browser, such as your theme and lesson settings. There are no advertising or analytics cookies.
Changes and contact
If we change this policy, we'll update the date at the top, and tell you in the app when a change matters. Doodo is run from India.
