In short: WizLook collects no usage data whatsoever. There is no analytics in the app, no counters, no events, no crash reports, and no opt-out switch — because there is nothing running to switch off. The files you open — their names, where they are, and what is in them — never leave your Mac, and the Quick Look previews never touch the network at all. What the app does talk to, it lists in About WizLook, and this Policy takes each in turn: Google's own pages when you open a Google Drive document (section 5), pictures on the web that a Markdown file or a notebook links to (section 6), Dodo Payments, to check your licence key (section 7), and our update feed, once a day (section 8).
This Privacy Policy explains how WIZHUT TECH SINGLE MEMBER P.C., operating under the name Wizhut.tech ("Wizhut.tech", "we", "us", or "our"), handles information in connection with your use of the WizLook application for macOS and its Quick Look extension (the "App"). It applies to the App and to the WizLook pages on wizhut.tech. It does not apply to any other product or service we operate, which are governed by their own notices.

2. What the App does
WizLook is a read-only viewer for macOS. It opens the placeholder files Google Drive for desktop leaves in a synced folder, showing each as the document itself through Google's own pages. It renders Markdown, reStructuredText and AsciiDoc, draws Excalidraw drawings, JSON Canvas boards and Mermaid and Graphviz diagrams, shows Jupyter notebooks with the outputs they were saved with, and lays out data files and source code. Its Quick Look extension shows the same files when you press Space in the Finder.
Everything except the Google Drive documents is drawn on your Mac, by the App, from the file itself. None of it involves us, and none of it needs a network connection.
3. Our approach: the burden of proof is ours
A viewer sees whatever you open in it: notes, notebooks, configuration files with their secrets in them, private documents. We think that makes the burden of proof ours rather than yours — so rather than ask you to trust a policy, the App names everything it talks to over the network in About WizLook, where you can read it without visiting this page. This Policy is the same commitment in legal form, and the two are kept in step deliberately.
Concretely, the App transmits none of the following to us or to anyone else:
- the names of the files you open, the folders they are in, or anything inside them;
- the list of files you have opened recently;
- what you read, scroll to, fold away or export in a document;
- how often you use the App, which kinds of file you open, which features you use, or how long a session lasts;
- usage, diagnostic, analytics, crash, or telemetry events of any kind;
- any installation, device, advertising, or session identifier.
The one exception is in the nature of a Google Drive placeholder: it is a pointer to a document Google holds, and to show that document the App follows it to Google, as section 5 explains. There is no analytics or crash-reporting software bundled in the App, and no advertising or attribution SDKs. This is not a retention period that could be shortened or lengthened later — the data is never created, so there is nothing to hold, breach, disclose, or subpoena.
4. The files on your Mac
4.1 Reading a file
WizLook opens a file read-only and never changes it. It renders the file itself, with JavaScript turned off, and nothing inside a file is ever run — no scripts, no notebook kernel, no diagram code. macOS's App Sandbox lets the App read the files you open and not the folder around them, which is why a picture stored next to a Markdown file shows as a placeholder. The App asks for no permission in System Settings.
4.2 Quick Look
macOS runs the App's Quick Look extension in a sandbox with no network access, so every preview is drawn from the file on your Mac. A Google Drive document previews from the copy the App kept the last time it showed that document (section 5.3), and a picture on the web shows as a placeholder. Quick Look previews never touch the network.
4.3 File › Export…
Export is the only way the App writes a file. It saves a drawing or a diagram as an image, a PDF or an SVG file, made on your Mac, under the name and in the folder you choose in the save panel — and writes nothing else.
4.4 What the App keeps
The list of recently opened files, where each window was, and the App's preferences stay on your Mac, where macOS keeps them for every app. What the App stores itself — its licence file, its Google sign-in and its Quick Look copies — is inside its own folder, ~/Library/Containers/com.wizlook.app.
5. Google Drive documents
5.1 Opening a document
A Drive placeholder holds little more than the document's address at Google and the account it belongs to. To show the document, the App opens Google's own page for it, on docs.google.com or drive.google.com, in its window — read-only, with every way into Google's editors turned away.
That page comes from Google like any web page. Google receives the request — the document's address, your Google sign-in if you have one in the App, and the technical details every request carries, including your IP address — and the page runs Google's own scripts. What Google does with that is governed by Google's Privacy Policy; none of it reaches us.
5.2 Signing in to Google
A document that is not shared with anyone who has the link needs you to be signed in. WizLook › Sign In to Google… opens a window that shows Google's own sign-in pages and nothing else. You type your email address and password into Google's page, as you would in a browser: they go to Google, the App's own code never reads them, and we never receive them.
Google keeps you signed in with cookies, which stay in the App's own web storage on your Mac, apart from Safari and every other browser. The App looks only at whether Google's sign-in cookies are there, to tell you whether you are signed in; it does not read your account. WizLook › Sign Out of Google… deletes those cookies and every other piece of site data the App holds, along with the copies described next.
5.3 Copies for Quick Look
When a window shows a Google Doc, Sheet, Slides deck or Drawing, the App asks Google for a PDF of it, through the same sign-in, and keeps it in its own cache on your Mac, so that pressing Space on the placeholder later shows the document. Each copy is at most 50 MB, and the cache keeps the newest hundred, no more than 500 MB in all. Beside them the App notes whether you are signed in to Google, yes or no, so a preview can say what it takes to show more. The copies never leave your Mac, and signing out of Google deletes them, since they may hold private documents.
6. Pictures and links in a document
A Markdown file or a Jupyter notebook can show pictures that live on the web, by their address. The App's window loads them, as a browser would, so the server that holds a picture receives a request for it, with the technical details every request carries, including your IP address. Which servers those are is decided by whoever wrote the file. Pictures stored inside a file — in a drawing, or in a notebook's saved outputs — need no connection, and Quick Look never loads a picture from the web.
Clicking a link in a document opens it in your default browser. The Help menu opens these pages, or a draft email to our support address in your mail app; the draft names your version and edition of WizLook, your version of macOS and whether your Mac has Apple silicon or Intel, so that we can answer, and nothing is sent unless you send it.
7. Your licence
WizLook is a paid app, and the licence check is how the App knows it has been bought. That is not analytics, but it deserves the same precision.
7.1 What is sent, and to whom
- On activation: the App sends your licence key and this Mac's name — the name macOS shows in Sharing settings — to Dodo Payments, our payment and licensing provider. The name labels the activation, so it is clear which Mac holds your key; if that name identifies you, that is because you named your Mac after yourself, and you can rename it before activating.
- On each launch: the App re-checks the same key, scoped to the activation created for this Mac. Nothing else is sent, and nothing at all is sent while you read.
- On deactivation: About WizLook → Deactivate This Mac asks the provider to release this Mac's activation, so the key can be used on another machine.
These requests carry your licence key and the activation identifier, and nothing else: no file names, nothing about the documents you open, no usage information. As with any network request, the receiving server also sees the technical details every request carries — including your IP address.
7.2 What is stored on your Mac
The App keeps one file, ~/Library/Containers/com.wizlook.app/Data/Library/Application Support/WizLook/license.json, holding your licence key, the activation identifier for this Mac, the product identifier and name, the name and email address on your purchase as the provider returned them, and the dates of activation and of the last successful check. It stays on your Mac; we never receive it. Deactivating this Mac deletes it.
The App also stores its own preferences — such as when it last checked for an update — in the standard macOS preferences store for the App, on your Mac.
7.3 Working offline
If the licensing server cannot be reached, WizLook keeps working for a further 14 days on the strength of the last successful check, so that a flight or an outage does not lock you out of your own files.
7.4 Payment
Dodo Payments acts as merchant of record for the sale and handles the payment itself. We never see your card details. The email address you give at checkout is held by that provider under its own privacy notice and our agreement with it, and reaches us as part of the record of a sale.
8. Updates
The App checks for new versions through the Sparkle update framework, once a day and whenever you choose Check for Updates…, by fetching an update feed we host and downloading the release from the same place. As with any download, the server serving those files sees the technical details of the request, including your IP address, and the App version making it.
Sparkle's optional anonymous system profile — which would report things like your macOS version and hardware model — is not enabled, so no profile is sent. Every update is verified against our signing key before it is installed.
9. This website
The WizLook pages on wizhut.tech are part of this site and follow its analytics practice: nothing that identifies you is stored or read until you accept the consent banner, and you can change your answer at any time using "Manage analytics preferences" in the footer. No advertising tag exists on this site. The banner itself explains what is collected in each of the three states.
Downloading the App from this site is a request to our download host, which sees the same technical request information any web server does.
10. Purposes and legal basis
Where the GDPR applies, we rely on the following legal bases:
- Performing our contract with you (Article 6(1)(b)) — activating and validating your licence, delivering your key, providing updates, and dealing with support requests and refunds.
- Complying with legal obligations (Article 6(1)(c)) — keeping the accounting and tax records a sale requires.
- Our legitimate interests (Article 6(1)(f)) — protecting our licences against abuse, keeping the App and our infrastructure secure, and establishing, exercising or defending legal claims. We have considered your interests and rights against ours, and the processing involved is limited to a licence key and an activation record.
- Your consent (Article 6(1)(a)) — website analytics only, and only after you accept the banner. You may withdraw it at any time.
There is no legal basis to describe for usage data, because we process none. What Google receives when the App opens its pages, it processes under its own Privacy Policy.
11. Recipients
We do not sell personal data, and we do not share anything about you with third parties for advertising purposes. Since the App collects no usage data, there is no usage data that could be shared, sold, or disclosed.
We may disclose limited information, where necessary, to:
- our payment and licensing provider, Dodo Payments, as described in section 7;
- infrastructure, hosting, download, email, and support providers that help us operate the App and this site;
- professional advisers such as accountants, auditors, lawyers, or insurers, where necessary for our legitimate business or legal purposes;
- public authorities, courts, regulators, or law enforcement bodies, where we are legally required to disclose or where disclosure is necessary to establish, exercise, or defend legal claims.
Where a provider processes personal data on our behalf, we put appropriate contractual and security safeguards in place and they may process it only on our instructions.
When you open a Google Drive document, or a document with pictures on the web, the request goes from your Mac to Google or to the picture's server directly, as sections 5 and 6 describe. It does not pass through us.
12. International transfers
The App transmits no usage or diagnostic events to us, so there is no such data for us to transfer. The limited licence and purchase information we process is handled within the European Union or European Economic Area, or under appropriate safeguards — such as the European Commission's standard contractual clauses — where our payment and licensing provider operates outside it. Where Google processes what it receives when you open its pages is set out in Google's Privacy Policy.
We do not otherwise transfer personal data we control outside the EEA unless appropriate safeguards are in place or the transfer is permitted by applicable law.
13. Retention
We hold no usage or diagnostic events, so there is nothing of that kind to retain or delete.
Records relating to your licence and purchase are kept for as long as the licence is valid, and afterwards for the period our accounting, tax, and legal obligations require, or as long as needed to establish, exercise, or defend legal claims. Support correspondence is kept for as long as it is useful to answer follow-up questions, and then deleted.
Everything stored on your Mac is under your control: signing out of Google deletes the App's Google sign-in and its Quick Look copies, deactivating this Mac deletes the licence file, and deleting the App and its folder in ~/Library/Containers removes the rest of what it stored.
14. Security
We maintain technical and organisational measures appropriate to the limited information we process — access controls, limited internal access, encrypted transport for licence checks and downloads, and cryptographic signing of every update. The App runs in macOS's App Sandbox, renders documents with JavaScript turned off, and lets nothing inside a file run. It is signed and notarized by Apple, so macOS can verify it has not been tampered with since we built it.
No method of transmission or storage is completely secure. The strongest protection we can offer here is structural rather than procedural: the files you open, their names, and what is in them are never collected in the first place.
15. Your rights
Subject to applicable law, you have the rights of access, rectification, erasure, restriction of processing, objection to processing based on legitimate interests, and data portability, as well as the right to withdraw consent where processing is based on it, and the right to lodge a complaint with a supervisory authority.
In practice the only personal data we are likely to hold about you is your purchase record and any correspondence you have sent us. Because the App collects nothing that identifies you, we may be unable to locate anything without the email address or licence key used at purchase; we will say so if that is the case. Your Google account, and what Google records when you open its pages, are held by Google, so requests about them are best made to Google.
To exercise your rights, write to privacy@wizhut.tech. You may also complain to your local data protection supervisory authority — in Greece, the Hellenic Data Protection Authority (www.dpa.gr); elsewhere in the EU or EEA, the authority for your country of residence, place of work, or the place of the alleged infringement.
16. Minors
WizLook is intended for adults working on a Mac and is not directed at children under the age of sixteen (16). We do not knowingly process personal data from children. If you believe a child has provided us with personal data, write to privacy@wizhut.tech and we will delete it.
17. Changes to this Policy
If the App ever begins to handle information differently, we will update this Policy and the "Last updated" date above before that version is released, and note the change on the release log. Adding any form of usage collection would be a material change to the promise this page makes, and we would say so plainly rather than quietly amending a paragraph.
