Privacy policy

Last updated 22 October 2026

• Artwork and customer files stay on your computer. DayZu Impose never uploads them.
• The app goes online only to check for a new version, when you write to us in the chat, if your shop connects to the DayZu Hub to send job cards and keep the shop's setup and History, and, if you agreed, to send a report when a file cannot be opened: never files or file names.
• The DayZu Hub keeps your shop's records for your shop only. Other shops, and our team, do not see them.
• No ads, no tracking, and we never sell or rent anyone's information.

1. Who we are

DayZu (the DayZu Impose app, the website dayzu.ai and the DayZu Hub at app.dayzu.ai) is made by DHB PTY LTD, an Australian company ("we", "us").

2. DayZu Impose, the app on your computer

• Your files: opening, checking, laying out, adding bleed and enlarging pictures with AI all happen on your computer. Files are not sent anywhere.
• New versions: once a day the app asks dayzu.ai whether a newer version exists. The request carries no identifier, no version number and no file names. Like any website, our host sees your internet address. You can turn this off in Settings.
• The chat: when you write to us from the app, we receive what you wrote, the app's version and the name of your operating system. App details (version numbers and recent error codes) go only if you tick "Attach app details". Never a file.
• Problem reports (in the app and on app.dayzu.ai): the first time a file cannot be opened, you are asked whether a report of such problems may go to the DayZu team, so a later version can open files like it. The answer is kept on that computer (on app.dayzu.ai, in that browser) and can be changed in Settings. A report holds the problem's code, the app's versions, the name of your operating system, and how the file is built: the program that made it, its sizes and page boxes, its fonts (their names, and whether they are included), its pictures (pixels, colour, compression), its links, layers and form fields (how many, of what kind), and the order of its drawing commands without what they draw. Never the file, its name (only its type, such as .pdf), its words or pictures, its title or author, or who you or your customers are. "What is sent?" beside the question shows a report exactly as it would go. Your internet address is kept only as a one-way code that changes every day, to stop abuse.
• Connecting to the DayZu Hub happens only if you press Connect. The app then sends the computer's name, your Windows user name and a public key, so the shop's owner can recognise the computer before approving it. After that it sends job cards: the customer's name, the job's name without its file type, the job type, its status and quantity, and numbers about the printed sheet (size, pieces, sides). It also keeps the shop's setup and History the same on each of the shop's computers and on app.dayzu.ai: the shop's name, presses, kinds of fold and recipes, and for each job in History its settings, its name without its file type, its customer and quantity, and each of its files known only by a fingerprint of what the file holds (SHA-256), so the very same file is recognised when you choose it again. Never files, file names or folders. What belongs to one computer (its folders, and whether an AI may look at a page to find fold lines) stays on it. The computer's private key stays on the computer.
• DayZu Impose in your browser (app.dayzu.ai): the same engine runs inside the web page. Opening, checking and laying out files happen in your browser, on your computer; files are not uploaded. Your open jobs, their files and History are kept in that browser's own storage on that computer, so clearing the browser's site data removes them. Laying out needs no account. Exporting asks you to sign in with Google once (section 3); if you are in no shop, we keep only that sign-in (your name and e-mail address), never anything about your jobs or files.

3. The DayZu Hub (app.dayzu.ai)

• Signing in with Google: Google tells us your name, your e-mail address and that the address is verified. We receive nothing else from your Google account. You stay signed in for up to 30 days, or until you sign out.
• Your shop's records: the shop's name and country; its members and their roles; its customers (what the shop enters on each customer's card: names, contact person, phone, e-mail, billing address, business or tax number, payment terms, category, notes and briefs); its job cards (production stages, custom labels and saved filters, quantities, due dates and production or delivery notes); its invoices and quotes (who they are for, their lines and amounts, payments recorded, what was shipped, whether and to whom they were e-mailed) and its invoice settings (business details, logo, bank account, numbering); a customer taken off the list, or an invoice deleted, is kept out of sight so that old invoices still name it and no invoice number is given twice; its setup and History as described in section 2, and each person's own choice of language, unit and light or dark screen; invitation links; the computers it connected (name, Windows user, the internet address and country they connected from, when last seen); and a log of who did what, kept as identifiers rather than contents.
• Your shop's customer chat (only if the shop connects its own LINE Official Account or Facebook Page): its conversations (the names and profile pictures LINE or Facebook gives, the messages, the ad a customer came from when they wrote from a Facebook ad, and the order notebook of each conversation); pictures customers send stay with LINE or Facebook and are fetched when someone opens them. A Facebook Page is connected by a person of the shop who signs in with Facebook and allows DayZu to read and answer that Page's messages; DayZu keeps only that Page's access key, locked, and lets go of it when the shop disconnects the Page. If the shop turns its chat assistant on, a conversation and what the shop keeps about that customer reach an AI provider (section 5) each time it drafts or sends an answer. Pictures the shop sends are kept so that LINE can fetch them: sample pictures until the shop takes them off, a picture a person sends for 7 days. A PDF a person sends is kept for 7 days too: LINE cannot carry a file, so the customer gets a link to open it.
• Kept apart: each shop's records are stored separately. People see only the shops they belong to, and only what their role allows.
• What our team sees: to run the service and help shops, our team keeps an account list: each shop's name and country and when it joined; each member's name, e-mail address and role, and when they joined; the computers the shop connected and when each was last seen; the log of who did what, kept as identifiers rather than contents; how many customers, invoices and messages the shop has; the use numbers below; and whether each member accepted the Terms. Our team does not open a shop's customers, job cards, invoices, quotes, chat or files, except when the shop's owner asks us for help or the law requires it. The account list opens only for one DayZu team account, behind a second sign-in step, and each time it is opened is logged.
• How the service is used: to see whether DayZu works for shops and what it costs to run, the Hub keeps the day each person last used it (a date, not a time) and the version of DayZu each connected computer runs. Each night it also counts, from the shop's own records, how many job cards, invoices and quotes were made, invoices sent, and chat messages received and sent on each day, and each month how many times the assistant and the chat's AI drafts were used and what they cost. These are numbers only: nothing a record says is copied. Daily numbers are kept for 90 days, then only as monthly totals. They are not used for advertising and not given to anyone else.
• Accepting the Terms: when you create a shop, we ask you to tick a box to accept the Terms of use and this policy. A shop's owner who has not accepted the current version (for example, after either page changes) is asked once when they next open the Hub. We keep that you accepted, when, and which version.

Owner reply learning (private pilot): if your shop's owner turns it on, successful replies by that owner are kept with the customer's question, recent text context and the assistant's original draft, if available. An AI provider may suggest a reusable example from that text for the owner to inspect. Only examples the owner approves are used for later relevant replies, within that shop or the chosen conversation. The owner can revise or withdraw approval and turn capture and use off. These records and review history remain in the shop's own data and backups; they are never shared as examples with another shop.

4. The chat on dayzu.ai and in the app

Messages are stored on dayzu.ai so we can answer. An AI assistant drafts answers from the DayZu guide; the messages reach an AI provider through OpenRouter, Anthropic or OpenAI, set so that providers that keep or learn from messages are not used where the service allows that choice. A person from our team may read and answer. Your internet address is kept only as a one-way code that changes every day, to stop abuse. A conversation is deleted after a year without messages.

5. Who keeps information for us

• Cloudflare, Inc. runs dayzu.ai and the DayZu Hub. Information may be stored or processed in Australia, elsewhere in Asia-Pacific, or in the United States.
• Google signs people in to the Hub.
• AI providers for the chat, as in section 4, and for a shop's chat assistant, as in section 3.
• LINE carries the messages of a shop that connects its LINE Official Account.
• Meta (Facebook Messenger) carries the messages of a shop that connects its Facebook Page.

We do not share anyone's information with advertisers or data brokers.

6. Information about a shop's customers

A shop decides which details of its own customers to keep in the DayZu Hub, and is responsible for having the right to keep them. We keep them only to run DayZu for that shop, following its instructions. Under Thailand's Personal Data Protection Act the shop is the data controller and we are its data processor. A shop's customer who wants to see, correct or remove their details should ask the shop; we help the shop do it.

7. How long we keep things, and deleting them

• A shop's records stay while the shop uses DayZu. The shop's owner can ask us to delete the shop, or one person's details, at any time.
• You can ask us to delete your account. We delete from our live systems within 30 days. If we keep backups, they expire within 35 days.
• Codes to connect a computer last 10 minutes; invitation links 48 hours.
• Problem reports are kept for up to a year, and of each kind of problem only the latest 20.
• Daily use numbers (section 3) are kept for 90 days, then as monthly totals while the shop uses DayZu. The record that you accepted the Terms is kept while your account exists.

8. Keeping it safe

Everything travels encrypted (HTTPS). Sign-in sessions and invitation links are stored only in a scrambled (hashed) form, and a connected computer proves itself with its own key. No system is perfectly secure: if a breach is likely to harm you, we will tell you and the regulator as the law requires, including Australia's Notifiable Data Breaches scheme and Thailand's PDPA.

9. Your rights

You can ask to see the information we hold about you, to correct it or to delete it, by writing to [email protected]. If you are not happy with our answer, you can complain to the Office of the Australian Information Commissioner (oaic.gov.au) or, in Thailand, the Personal Data Protection Committee (pdpc.or.th).

10. Cookies and the like

The website remembers your chosen language in your browser. The DayZu Hub uses one cookie to keep you signed in, and a short-lived one (10 minutes) while you sign in with Google. There are no advertising or analytics cookies. On app.dayzu.ai, DayZu Impose keeps your open jobs, their files and History in your browser's storage on your computer (section 2); none of it is sent to us.

11. Children

DayZu is made for businesses and is not meant for anyone under 16.

12. Changes

We will update this page and its date when something changes, and say so in the app or the Hub when a change matters to you.

This policy is in English and Thai. If the two differ, the English text applies.
