On your devices
Your favourites, scanned drawings and settings stay in the app, and in your own iCloud if you use it.
Line Art Printer · PrivacyEffective 11 November 2026
Your drawings stay yours.
Line Art Printer has no accounts, no ads and no tracking. This page lists everything that leaves your iPhone or iPad, who receives it, and how long it is kept.
Searches
The words you search for go to our catalogue server, which keeps no history of them.
AI edits
The page or drawing you edit, and what you ask for, go to our server and to OpenAI, or to Alibaba Cloud if OpenAI can’t. We keep neither.
Children
No ads, no tracking, no chat. A grown-up agrees before the first AI edit.
Who we are
Line Art Printer is made by Calogero Cascio, an independent developer in Milan, Italy, who is responsible for the data described here. Write to privacy@linelark.com with any question.
What stays on your device
Your favourites, the drawings you scan or save to the gallery, your print and display settings and the monthly search count are stored in the app on your device. They are not sent to us and they are removed when you delete the app.
If you are signed in to iCloud, the app keeps your favourites and scanned drawings in your private iCloud database so they appear on your other devices. That happens between your devices and Apple; we cannot see your iCloud data. Apple’s privacy policy applies to iCloud.
Searching the catalogue
When you search, the words are sent to our catalogue server at lineart.linelark.com, which runs on Cloudflare. Like every web server it also receives your IP address. We use both only to answer the search and to limit abuse; request logs are kept by Cloudflare for a few days and are not linked to you or used to build a profile.
The pages in the catalogue are published by other websites, and the app loads each image from the site that publishes it. That site receives your IP address when the image loads, as it would in a web browser.
AI edits
Everyone can make two AI edits a week for free; AI Premium gives 50 a month instead. Before the first one, the app asks you to agree. When you edit a page or a scanned drawing with AI, the image and the words you type are sent to our server and passed to OpenAI, which checks the request is suitable for children and makes the edit. The finished page is checked the same way and sent back to the app. If OpenAI cannot make the edit, our server sends the same image and words to Qwen Image, run by Alibaba Cloud in Singapore, which makes it instead; OpenAI still checks the request and the finished page.
We do not store your images, words or edited pages on our server. OpenAI may keep them for up to 30 days to detect misuse, and then deletes them; it does not use them to train its models. OpenAI’s handling is described at openai.com/policies. When Alibaba Cloud makes an edit, Alibaba Cloud’s privacy policy describes how it handles the request.
To count the free edits, the app sends a random number created when it was installed. Our server keeps only a scrambled (hashed) form of it, with the number of edits used each week. It cannot be traced back to you.
With AI Premium, the app also sends the App Store’s signed record of your subscription. It contains the product, dates and a transaction number from Apple, but not your name, email or Apple Account. We keep only a count of the edits used each month for that transaction number, so the monthly allowance works on all your devices.
Purchases
Subscriptions are sold and managed by Apple. We never see your payment details. Apple’s privacy policy applies to the purchase itself. AI credit packs sold by earlier versions are no longer offered, and their balances, which were kept only on your device, have been removed.
Camera, photos and printing
The camera is used only when you scan a drawing, and the scan is processed on your device. When you pick a photo, the app receives only that photo. The app adds to your photo library only when you choose to save a drawing there. Printing goes from your device to your printer through AirPrint, and sharing goes only where you send it.
No tracking
Line Art Printer contains no advertising, analytics or tracking tools, does not use the advertising identifier and does not track you across other companies’ apps or websites, whatever you answer if iOS asks for permission to track.
Children
Line Art Printer is made for parents and teachers to find, print and colour pages with children. It has no ads, no chat and no way for children to share anything with strangers. We do not knowingly collect personal information from children. A child’s drawing leaves the device only if a grown-up chooses to edit it with AI, as described above.
Your rights
Because we hold nothing that identifies you, there is usually nothing to look up. If you live in the European Union or the United Kingdom you have the right to ask what we hold, to have it corrected or erased and to complain to your data protection authority (in Italy, the Garante per la protezione dei dati personali). To ask us to erase the edit count tied to your subscription or your device, write to privacy@linelark.com.
Changes
If this policy changes, the new version is published here with a new date. Changes that affect what leaves your device will also be described in the app’s release notes.
