NODUPrivacy Policy
Last updated: 6 November 2026
NODU ("we", "our", "the app") lets you open, convert, and preview design files (CorelDRAW, Illustrator, Photoshop, and common document formats). This page explains what happens to your data when you use the NODU website or Android app.
Files you open or convert
When you open or convert a file, it is sent to our server for processing (using LibreOffice, GIMP, and CorelDRAW running on that server) and the result is sent back to your device. We do not keep your files longer than needed:
- Uploaded files are processed and then deleted automatically as soon as the request finishes.
- The preview of a file you opened (and, for CorelDRAW, Illustrator and large files, the PDF it was drawn from, so it stays sharp when you zoom in) is kept in a private server cache for up to 24 hours, so the same file opens again quickly. It is then deleted automatically. Nobody looks at it.
- The "Move, resize & delete objects" tool keeps a working copy for up to 1 hour to let you make edits, then deletes it automatically.
- We do not view, share, sell, or use your files for any purpose other than producing the conversion or export you requested.
Making pictures editable (AI text reading)
When you make a picture editable (for example a poster or invitation, so its text can be changed), a copy of that picture may be sent to Anthropic's Claude AI service to read the words in it. Only the picture is sent — no name, account or contact details. Anthropic processes it under its commercial terms to return the text and does not use it to train its models; see Anthropic's privacy policy. To rebuild the background behind the text and the movable parts (so it matches when you move or delete them), a smaller copy of the picture may also be sent to OpenAI's image service; OpenAI does not use data sent through its API to train its models by default — see OpenAI's privacy policy. We do not keep the picture after the request is finished.
Font Finder
Images you use with Font Finder (to identify a font) are processed on our server to run the matching and are not stored afterward. If you choose to download a matched font, that request goes to Google Fonts directly — see Google's privacy policy.
Nobot help chat
Questions you type to Nobot (the help button at the bottom left) are sent to our server to write the answer. When the AI answer is switched on, the question and the last few messages of the chat are also sent to Anthropic (the maker of the Claude AI) only to write that answer. We keep the question text, the page you were on and a scrambled (one-way hashed) code of your internet address for up to 90 days to see what users need help with and to stop misuse; we do not keep your real IP address with it. Please do not type passwords or personal details into the chat.
Feedback you send us
If you use the in-app Feedback form, we store the message you write, an optional screenshot you attach, an optional e-mail address if you choose to give one (used only to reply to your message, for example to tell you a problem is fixed), the page you were on, and basic technical information (like your browser's user-agent string) so we can understand and fix the issue. This is kept to help us improve the app; contact us (below) if you'd like a feedback submission removed.
Your JUST NODU account
In the Android app you can create an account with your email address, mobile number and a password (and your name, if you want). We store these to sign you in, together with when you signed up and last used the app, how many times you signed in, and the kind of device (for example "Android app"). Your password is stored only in a scrambled, one-way form (scrypt hash) that nobody, including us, can read back. We use these details only to run your account and to help you, for example if you forget your password. We do not sell them, share them with other companies, or use them for advertising, and we do not send marketing messages.
You stay signed in on your phone for up to a year. You can sign out, change your password or delete your account at any time in the app (account button), or on the delete account page. Deleting removes your account details from our servers immediately.
App lock: if you turn on App lock, your fingerprint, face, pattern or PIN is checked by your phone's own Android security. JUST NODU never receives or stores it.
Advertising (website)
The justnodu.com website shows ads from Google AdSense. Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this website or other websites. Google's use of advertising cookies enables it and its partners to serve ads to you based on your visits to this and/or other sites on the Internet. You can opt out of personalised advertising in Google Ads Settings, or opt out of some third-party vendors' use of cookies at aboutads.info. Where required by law, you are asked for consent before personalised ads are shown. See how Google uses information from sites that use its services. The Android app shows ads from Google AdMob.
Measuring our own Google ads: we advertise JUST NODU on Google Search. To know whether those ads help people, the justnodu.com website loads the Google tag (Google Ads conversion measurement). It uses cookies to note that a visit came from one of our ads and sends Google a single "opened a file" event when you open a file. Your file, its name and anything you type are never sent to Google. Our own website also counts, for our dashboard, how many visits came from our ads and how many of those visitors opened a file (only these counts and the page, nothing about you or your file). The Google tag is not loaded inside the Android app, and it is not loaded when your browser sends a Global Privacy Control signal. You can also block it with your browser's cookie settings or opt out in Google Ads Settings.
What we don't do
- The website needs no account. The Android app may ask you to create one (email, mobile number and password, described above).
- We don't sell your data, and we don't share it with third parties for marketing. Apart from the advertising and ad-measurement cookies described above, we don't use tracking.
- We don't request access to anything on your device beyond what a feature needs in the moment — e.g. the camera only opens when you tap Font Finder's camera option, and only to take that one photo.
Android app permissions
The NODU Android app requests internet access (to talk to justnodu.com) and, only when you use the camera-based Font Finder feature, camera access for that single photo. It does not request contacts, location, microphone, or background access.
Changes to this policy
If this policy changes, we'll update the date at the top of this page.
