Linefy · PrivacyEffective 11 November 2026
Linefy 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.
Your pages, colours, saved images, recent searches and the artist’s name stay in the app on this device.
The words you search for go to our catalogue server, which keeps no history of them.
What you type, and any photo you choose, go to our server and to OpenAI to draw the page, or to Alibaba Cloud if OpenAI can’t. We keep neither.
A grown-up’s permission is asked before purchases, outside links and the first AI page.
Linefy 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.
The pages you colour, their colours and drawings, the pages you save for later, your recent searches, the daily search count and the first name you may type at the start are stored only in the app on your device. They are not sent to us and they are removed when you delete the app.
Linefy does not use iCloud to sync your library. Once, if you used Linefy 4, the app reads the pages and favourites that version saved in your private iCloud database and copies them into the new library. That happens between your device and Apple; we cannot see your iCloud data.
When you search or open a topic, 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.
When an image fails to load, or you report one, the app sends the image’s number, the reason and a random number created when the app was installed. The server stores that number only in a scrambled (hashed) form, to count each device once. It cannot be traced back to you.
Everyone can make two AI pages a week for free; Premium AI gives 50 a month instead. Before the first one, a grown-up is asked to agree. When you make a page, the words you type, and the photo or drawing you choose if any, are sent to our server and passed to OpenAI, which checks the request is suitable for children and draws the page. The finished page is checked the same way and sent back to the app. If OpenAI cannot draw the page, our server sends the same words, photo or drawing to Qwen Image, run by Alibaba Cloud in Singapore, which draws it instead; OpenAI still checks the request and the finished page.
We do not store your words, photos or 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 draws a page, Alibaba Cloud’s privacy policy describes how it handles the request.
To count the free pages, the app sends the random number created when it was installed (the same one used for reports). Our server keeps only a scrambled (hashed) form of it, with the number of pages used each week.
With Premium AI, 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 pages used each month for that transaction number, so the monthly allowance works on all your devices.
Subscriptions are sold and managed by Apple. We never see your payment details. Apple’s privacy policy applies to the purchase itself.
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. Linefy adds to your photo library only when you tap Save to Photos.
Linefy is made for families. It has no ads, no analytics or tracking tools, no chat and no way for children to share anything with strangers. A grown-up’s answer to a question is required before purchases, links that leave the app and the first AI page. We do not knowingly collect personal information from children, and the name a child may type stays on the device.
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 page count tied to your subscription or your device, write to privacy@linelark.com.
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.
