Privacy Policy

Flashdrop ("we", "us") turns your class notes into quizzes and flashcards at flashdropai.com. This policy explains what we collect, why, who helps us run the service, and the choices you have. The short version: your notes are private to you, we use them only to make your study materials, and we never sell your data or show ads.

Who can use Flashdrop

Flashdrop is for students who are 13 or older. We ask for your birth month and year before you create an account, and we don't let anyone younger sign up. We don't knowingly collect personal information from children under 13. If you believe a child under 13 has given us information, email privacy@flashdropai.com and we will delete it.

What we collect

• Account details from Google sign-in (or Apple, if we add it): your name, email address and profile picture.
• Birth month and year, to confirm you're 13 or older. We don't collect your full birthday.
• Your study content: photos and files of your notes, pages you write on screen, the text we read from them, your corrections, the classes and topics you create, and the quizzes and questions made from them.
• Handwriting corrections: when you fix a word we misread, we save the before and after so we read your handwriting better next time.
• Handwritten answers you write with Apple Pencil, which we read to grade your answer.
• Usage records: how many pages and quizzes you process each day, used to keep the service fair and running.
• Device settings stored in your browser, such as light or dark mode.

We don't use advertising trackers, and we don't collect your location or contacts.

How we use it

• To read your notes and create quizzes, flashcards and practice tests for you.
• To improve how we read your own handwriting (your corrections only affect your account).
• To keep your work in sync across your phone, tablet and computer.
• To prevent abuse and keep the service running.
• To answer you when you contact us.

We don't sell your personal information, share it for advertising, or use your notes to train AI models.

Who helps us run Flashdrop

We use a small number of service providers, who process data only on our behalf:

• Supabase stores your account and study content (database and photo storage).
• Vercel hosts the website.
• Stripe processes Premium payments. If you upgrade, Stripe collects your payment details directly and we never see your card number. We keep only a link between your account and your Stripe customer record, and read your plan and renewal date from Stripe.
• Anthropic provides the AI that reads your notes and writes questions. We send it the note images and text needed for each request. Anthropic's commercial terms say it does not train its models on this data.
• Google handles sign-in (and Apple, if we add it).

Sharing quizzes

Your notes and quizzes are private by default. When you share a quiz, anyone with its link or code can open and take it, without an account. Shared quizzes show the quiz title, class name, questions and your first name, but not your notes, photos or email.

How long we keep it

We keep your content until you delete it or delete your account. You can delete individual notes and quizzes at any time. Deleting your account (Settings → Delete account) permanently removes your account, notes, photos, quizzes and progress from our systems. Backups are overwritten within about 30 days.

Your choices and rights

• Access and correct your content any time in the app.
• Delete notes, quizzes or your whole account in the app.
• Stop sharing a quiz by deleting it.
• Ask us for a copy of your data or anything else about your privacy at privacy@flashdropai.com. Depending on where you live (for example California or the EU), you may have additional rights, which we honor.

Security

Your data is encrypted in transit. Every account can only see its own notes and photos; this is enforced by the database, not just the app. AI keys and processing stay on our servers. No system is perfectly secure, so please keep your Google account secure.

Students and schools

Flashdrop is a tool students choose to use on their own. If a school or teacher asks students to use it, contact us at privacy@flashdropai.com about any agreements your school needs.

Changes

If we change this policy in a meaningful way, we'll update the date above and tell you in the app before the change takes effect.
