Privacy Policy

This policy explains what Crayonshot collects, why, and what you can do about it. We wrote it in plain words. Questions? Email crayonshot@evtsoy.com.

Who we are

Crayonshot (“we”, “us”) is an app that turns your photos into printable coloring pages. It is made by Crayonshot. You can reach us at crayonshot@evtsoy.com. This policy applies to the Crayonshot app and to this website.

The short version

  • Your pages and books are saved only on your phone.
  • When you make a page, the photo you pick is sent to OpenAI only to draw that page, and only after you agree in the app. We don’t keep your photo or the page on our servers.
  • There are no accounts. We use an anonymous ID so your free page and purchased pages work.
  • We don’t sell your data, show ads, or track you across other apps.
  • You can turn off AI drawing and usage analytics in the app at any time.

Data we collect

Stored only on your phone

Your coloring pages, books, book titles and app settings. They never leave your phone unless you save, print or share them yourself.

Sent to our backend (Supabase)

  • An anonymous user ID, created automatically. It is not linked to your name, email or Apple ID.
  • An install ID and your device’s vendor ID (an Apple identifier that is the same for our apps on your phone). We use them to give one free page per phone and to keep your pages after a reinstall.
  • Your pages ledger: the free page, purchased packs, pages used and refunds.
  • Page records: when a page was made, whether it worked, the option you chose (whole scene or just the subject), the AI provider’s name and its task ID, and an error message if it failed. These records contain no photos, no pages, no image links and no face data.

Purchases (Apple and RevenueCat)

Apple processes payments. We never see your card or Apple ID. RevenueCat receives the anonymous user ID and purchase details (product, transaction ID, price, date) so we can add your pages.

Usage analytics (PostHog)

If you leave “Share anonymous usage data” on, the app sends anonymous events such as “page made”, “shop viewed” or “purchase completed”, plus basic technical data (app version, device model, OS version). They are tied only to the anonymous ID. Turn it off in Settings and nothing more is sent.

Support emails

If you email us, we receive your email address and what you write.

Third-party AI: OpenAI

Crayonshot uses OpenAI to turn your photo into a coloring page. Before your first page, the app asks for your permission and shows this:

“To draw your page we send the photo you pick to OpenAI. It’s shrunk first and used only to make this page. OpenAI may keep it for up to 30 days for safety checks, then deletes it, and doesn’t use it to train its models. We don’t keep your photo or the page on our servers; the page is saved only on this phone.”

  • What is sent: only the photo you pick for a page (made smaller first) and the option you chose. Nothing else from your photo library.
  • When: only after you agree, and only when you make or redo a page.
  • How: your phone sends the photo to our server function, which passes it to OpenAI in memory and returns the page to your phone. We don’t store the photo or the page.
  • What OpenAI keeps: OpenAI may keep the photo and the generated page for up to 30 days to check for abuse, then deletes them. OpenAI doesn’t use them to train its models.
  • Turning it off: switch off “AI drawing” in Settings. Nothing is sent while it is off; you’ll be asked again before your next page.

OpenAI protects this data under its own terms and privacy policy: OpenAI Privacy Policy.

Photos of people

Photos you choose may show people, including children. Here is exactly how they are handled:

  • What is collected: only the photo you pick, while your page is being made.
  • Use: only to draw your coloring page. Never to identify anyone, for tracking, for advertising or to train AI models.
  • Shared with: OpenAI only, as described above.
  • Where it is stored: on your phone. We don’t store it on our servers. OpenAI may keep it for up to 30 days for safety checks.
  • Deleting it: delete the page in the app or use Settings → Delete my data. OpenAI deletes its copy within 30 days.
  • No face data: Crayonshot doesn’t create face templates or biometric data, and doesn’t use the camera’s face-tracking features.

Only use photos of yourself, your family, or people who said yes.

How we use data

  • To make your coloring pages (performing our service to you).
  • To give one free page per phone, add purchased pages, and refund failed pages.
  • To prevent abuse, for example limits on how many pages can be made at once.
  • To understand which features are used and fix problems, only if analytics is on (our legitimate interest, which you can switch off).
  • To answer your emails.

Services we use

How long we keep data

  • Photos: not kept by us. OpenAI may keep them for up to 30 days, then deletes them.
  • Pages, books and settings: on your phone until you delete them or the app.
  • Anonymous ID, device IDs and page records: for as long as you use the app, so your pages keep working. Ask us to delete them at any time.
  • Purchase records: as long as needed for accounting and tax rules.
  • Analytics events: for as long as needed to understand app usage, then deleted.
  • Support emails: until your question is solved, plus a reasonable time for follow-ups.

Your choices and rights

  • AI drawing: Settings → AI drawing.
  • Analytics: Settings → Share anonymous usage data.
  • Delete data on your phone: Settings → Delete my data, or delete the app.
  • Delete server records: email crayonshot@evtsoy.com. Purchase records may be kept where the law requires.

Depending on where you live (for example under the GDPR in the EU and UK, or the CCPA in California), you may have the right to access, correct, delete or move your data, and to object to or limit how we use it. Email crayonshot@evtsoy.com to use these rights. You can also complain to your local data protection authority.

Children

Crayonshot is for parents, teachers and other adults, who choose the photos and make purchases. It is not directed to children under 13, and we don’t knowingly collect personal information from children. If you think a child has sent us personal information, email crayonshot@evtsoy.com and we will delete it.

No selling, no ads, no tracking

We don’t sell or rent your data. There are no ads in Crayonshot, and we don’t track you across other companies’ apps or websites.

Changes to this policy

We will update this page when the app changes how it handles data, and change the date below.
