Privacy policy

Manual CAD can read and edit drawings without an account. Cloud recovery is optional; drawings you open are kept privately to improve Nasji, as explained below. Local settings and recent-file history stay on the device; converters and AI requests send the data needed to perform their work as described below.

Optional cloud recovery

Cloud Autosave is an optional paid service included in Cloud Lifetime and AI Lifetime. It has no commercial file-size, storage or version-retention quota. Enable it in Cloud on each device. Changed open drawings are captured every 10 minutes while the app runs, and local saves also queue recovery copies. Existing local versions upload when you enable backup. NASJI stores complete model and layout data, display names and timestamps in private Cloudflare R2 storage. It does not store local paths or login credentials in these copies. Access requires your account; copies are compressed and integrity checked. Pausing uploads or refunding a purchase does not delete previous copies. Offline uploads retry from local versions, subject to device availability; changes not yet uploaded are not cloud protected. Cloud copies are not used to train AI. Ask [email protected] to delete them. Keep independent copies of important work.

How your drawings help us improve Nasji

Nasji gets better because of the real drawings people work on. When you open a drawing in the web CAD at nasji.com/cad or in the Nasjicad desktop app, a copy of the file you opened is kept in Nasji’s private cloud storage, together with snapshots of it as you save, and a timeline of the session: the commands you ran, when you ran them, whether they succeeded, the errors the app showed, the app version and platform, your account (or, without an account, a random device id) and the country derived from the network address.

We use this to find and fix the files and commands that break, to test every new release against real-world drawings, and to design, develop and train Nasji’s own features, including its AI features. It is not sold, not shared with anyone for their own purposes, and not used for advertising. This is separate from Cloud recovery above: recovery copies exist so you can restore your own work.

The copies are compressed, stored in a private bucket, and reachable only by a small number of Nasji staff through an audited admin tool; every access is logged. A file that many people open is stored once. We keep these copies for as long as they are useful for improving the product and at most three years, then delete them. Our legal basis under the UK GDPR is our legitimate interest in making a reliable product, and the performance of our contract with you.

You can object at any time: write to [email protected] and we will switch this off for your account and delete the copies and timelines already linked to it. If a drawing is confidential, we recommend asking us to switch it off before you open it.

What we receive when you use a converter

The converters send your file to our server for processing. The image-to-CAD converter, including DXF to DWG, may retain input files, results and technical conversion records for troubleshooting. The separate CAD conversion and drawing export tools remove their temporary working files after processing. Contact [email protected] if you need help with an uploaded file.

What an account holds

An account is created when you sign in with a code sent to your e-mail address, or with your Google account. In the Google case we receive your e-mail address and name from Google; we keep the address and use nothing else. The account holds the address, the time it was created and last used, the balance, the ledger of what was charged or credited, and the conversations you have with the agent, so that a drawing can be continued.

If you bring your own model key, it is stored encrypted and used only to call the provider you named; it is never shown again in full and never used for anything but your own requests.

Payments

Card and wallet payments are handled by Stripe, PayPal or Paymob on their own pages. We never see a card number. We keep the payment’s reference, amount and status so that the credit can be applied and a receipt sent.

Usage measurement

The site, the web CAD and the desktop app report how they are used: pages opened, tools used, whether the agent’s turn succeeded, the app version, a random device id, and the country and city derived from the network address. This is what tells us what breaks and what is worth building. The desktop app’s reporting can be turned off in its settings.

The site may also run third-party measurement and advertising tags — Google Analytics, Google Ads conversion tracking, Microsoft Clarity — which set their own cookies under their own policies. They are used to know whether an ad led to a sign-up, not to identify you to anyone.

E-mail

We e-mail you sign-in codes, receipts and notices about your balance. We may also write to you about your account: a welcome, a note when the agent failed you, an offer when the trial runs out. Every such letter has an unsubscribe link that stops all of them at once.

Cookies

We store a first-party browser identifier in a cookie and local storage to remember when your personal welcome offer starts and ends, including before sign-in. The deadline is stored on our server and linked to your account when you sign in. We do not use device fingerprinting for this offer.

One cookie keeps you signed in. One short-lived cookie carries a Google sign-in across the round trip. The measurement tags above set theirs. There is no advertising profile built here.

Who else sees data

The model providers that run the agent see the text of your request and the drawing context needed to answer it. The payment providers see the payment. The mail provider sees the address a letter goes to. No one is given your data for their own purposes, and nothing is sold.

Keeping and deleting

Your account and its data are kept while the account exists. Write to [email protected] from the account’s address and it is deleted, with its balance, ledger and conversations, within a few days. Payment records are kept as long as the law requires.
