Cookie policy

DALFAST Studio · DALFAST, s.r.o. · Last updated and effective: 12 November 2026

This policy explains the cookies and other storage the Studio uses on your device (browser storage, an in-browser database and an offline copy), and the requests your browser makes to outside servers. The same rules apply to all of them, not only to cookies. The Privacy policy explains the related personal data.

1 What we use, in short

We use storage only for features you use: staying signed in, keeping your work in your browser, remembering your choices, and the offline copy. We set no advertising cookies and allow no tracking by other companies unless you say yes: while we advertise the Studio on other sites, a banner may ask whether the advertising platforms may see which of our ads brought you here (section 6). Without your yes nothing from them loads, and we checked every part of the Studio for this: visiting, signing in, buying, working together, publishing and the outside services. One other optional feature, first-visit measurement, is off unless you switch it on (section 6).

2 Cookies

DSTUDIO (dalfast.studio): keeps you signed in. Set when you sign in; lasts up to 30 days or until you sign out. Only sent over HTTPS, not readable by scripts (HttpOnly), and not sent with requests from other sites (SameSite=Lax). Essential for the account you ask for.

dstudio_writer, dstudio_effort, dstudio_m_image, dstudio_m_voice, dstudio_m_video (dalfast.studio): remember the writing helper, effort level and picture, voice and video engines you chose, so the server uses them. Set only when you choose one; kept for one year or until you change it; sent only over HTTPS. Essential for a choice you made.

dsm_<website name> (on a website published with the Studio, under /s/<website name>/): lets a member into the members-only pages after entering the right password. Lasts 30 days. Only sent over HTTPS, HttpOnly, SameSite=Lax. Essential for the access the member asks for.

3 Storage in your browser

Your work (browser storage "dalfast-studio-v2" and the in-browser database "dalfast-media"): your projects, notes, uploads, brand kits, folders, recent activity, settings, and the pictures, sounds, videos and version history (up to 300 steps per project) inside your designs. The Studio needs this to work; it keeps your work on your device even when you are not signed in. It stays until you delete a project or clear this site's data in your browser. Pictures no project uses any more are removed automatically once a day.

Your settings and choices (inside "dalfast-studio-v2" and a few small entries): appearance, language and the translations already loaded for it ("dalfast.i18n.<language>"), the place, contact and organisation details you used in forms (up to six of each, to offer them again), your own reports to us ("dalfast.reports"), the name you typed when reviewing a design ("dalfast.reviewer"), and whether the offline copy is complete ("dalfast.offlineReady"). They stay until you change them or clear the site's data.

Live polls ("dalfast.voter"): a random code made only when you join or vote in a live poll during a presentation, so a vote counts once. It holds nothing about you.

For one browser tab only (session storage, deleted when you close the tab): start-up recovery, the "updated" message, a notice you closed, and whether you opened Advanced settings.

4 The offline copy (service worker)

The Studio installs a small script in your browser (a service worker) that keeps a copy of the Studio's own files, recent pictures from the Studio's library (the last 250) and the code libraries and fonts it has downloaded, so pages open quickly and keep working on a poor connection. It never stores your account data from our server. Old versions are removed when the Studio updates, and the script checks for updates every few minutes.

A complete copy for working without a connection is made only when you choose "Save to this device". You can remove the copies in Settings → Storage → "Free the offline copy", or by clearing the site's data.

5 Payments and outside services

Payments happen on Stripe's own secure page; no Stripe code runs on our pages. Stripe's cookies and privacy information: https://stripe.com/cookie-settings and https://stripe.com/privacy.

Some features ask an outside server for code, a model or a font the first time you use them. Your browser then sends that server your network address; we do not set cookies for them. They are: cdnjs (Cloudflare) and jsDelivr for code libraries (spreadsheets, PDF import, MP3 export, 3D, QR codes, icons and the on-device photo tools); Hugging Face for the models of the on-device photo tools; Google (storage.googleapis.com) for the face-finder model; Google Fonts for a font that is not stored with the Studio (loaded automatically when you open a design that uses such a font); Pexels and Pixabay for the small previews of stock videos and photos you search for. Google Drive and Dropbox, when offered for importing files, use their own sign-in windows. Continue with Google, when it is offered: when a sign-in or sign-up window opens, Google's sign-in button loads from Google (accounts.google.com), which receives your network address and may use its own cookies under its own policy (https://policies.google.com/privacy). Only if you press it does Google tell us your name, your email address and that Google has confirmed it; we use them only to sign you in or create your account, and no Google password or access to your Google account reaches us.

6 Your choices

First-visit measurement is optional and off unless you switch it on in Settings → Privacy & data → "Help improve the Studio". When on, it notes in your browser ("dstudio-act") which first steps you reached (opening, editing and saving a design) and uses a session code that changes after 30 minutes without activity; the events it sends hold no name, email, network address or browser details and are kept for up to 400 days. You can switch it off in the same place at any time; it then stops, and the note in your browser is deleted.

Advertising cookies are optional. The cookie notice asks once ("Essential only" or "Accept all", side by side); only if you press Accept all do the platforms we advertise with load their tag from their own servers and set their cookies: Google Ads (googletagmanager.com; cookies such as _gcl_au), Microsoft Advertising (bat.bing.com; _uetsid, _uetvid, MUID), Meta (connect.facebook.net; _fbp), TikTok (analytics.tiktok.com; _ttp), Pinterest (s.pinimg.com; _pin_unauth, _epik) and LinkedIn (snap.licdn.com; li_fat_id, bcookie). The banner names the ones in use at the time. They let us count, once each, a new account and a paid order (with its amount) that came from one of our ads; we switch off personalised advertising where the platform allows it. Each platform keeps its cookies for up to 13 months under its own policy (Google: https://policies.google.com/technologies/partner-sites; Microsoft: https://privacy.microsoft.com/privacystatement; Meta: https://www.facebook.com/privacy/policy; TikTok: https://www.tiktok.com/legal/privacy-policy-eea; Pinterest: https://policy.pinterest.com/privacy-policy; LinkedIn: https://www.linkedin.com/legal/privacy-policy). Your answer is kept in your browser ("dalfast.adsConsent", and "dalfast.cookieNotice" so the notice does not ask again); change it at any time in Settings → Privacy & data → Advertising cookies. "No thanks" means none of them ever loads.

Global Privacy Control: if your browser sends this signal, the Studio does not count your visits, does not run first-visit measurement even if you switched it on, never shows the advertising banner and never loads an advertising tag, and websites published with the Studio do not count your visit either.

You can also delete cookies and site data in your browser. Deleting DSTUDIO signs you out. Deleting the Studio's browser storage permanently deletes work that was never saved to an account or downloaded; work saved to your account is not deleted, but changes not yet saved may be lost.
