# Cookie policy

This page lists everything SumizAI stores on your device through a browser,
            what it is for, and how to switch it off. Before you choose, page views are
            counted without storing anything on your device; cookies are written only after
            you say yes. The desktop application sets no cookies at all and sends us nothing.

## What this covers

Three different things carry the name SumizAI, and they store very
                different amounts on your device. This document is precise about which is
                which.


                
                    **The website, `sumizai.com`** — the pages you
                    are reading now, including the blog and these legal documents. This is the
                    only place where analytics exist.
                    **The desktop application** — the macOS app. It sets
                    **no cookies**, it carries no analytics, no telemetry and no
                    crash reporting, and it sends nothing to us at all.
                    **The legacy web application, `app.sumizai.com`**
                    — the older, frozen product with accounts. It sets two strictly necessary
                    cookies and no analytics cookies.
                
                "Cookies" here is shorthand for anything written to your device by a
                website: cookies proper, and also `localStorage` entries. Storing
                anything that is not strictly necessary for a service you asked for requires
                your consent under the ePrivacy rules as implemented in Polish law; the
                personal data that analytics then collect is processed on the basis of that
                consent, Article 6(1)(a) GDPR. What happens to data more broadly is in the
                [Privacy Policy](/legal/privacy.html).

## Our approach: nothing is stored before you choose

Google Analytics and Microsoft Clarity are not in the page source. They are
                injected by one first-party script, `/assets/consent.js`, which runs
                on every page.


                **Before you answer, and if you refuse, both tools run in cookieless
                mode.** They count that a page was opened and send us that fact. What
                they do _not_ do is write anything to your device: no cookie, no local
                storage, no session storage, no identifier that would let anyone recognise you
                on your next visit. Google calls this state _Consent Mode advanced_ and
                marks the measurement as modelled; Microsoft calls it _cookieless mode_
                and gives each page view its own throwaway number. Consent law in Poland
                — art. 398 of the Electronic Communications Law, implementing art. 5(3)
                of the ePrivacy Directive — governs storing and reading data on your
                device, and in this state we do neither.


                **Only if you accept** do the cookies in the table below get
                written and does session replay start.


                **Your choice is not stored in a cookie.** It lives in your
                browser's `localStorage`, under the key
                `sumizai.consent`, first-party, and it never leaves your device. The
                record holds three things: a version number, whether you accepted analytics,
                and the timestamp of the choice.


                If `localStorage` is unavailable — private browsing, storage
                disabled — the choice cannot be remembered, so the banner appears again on your
                next visit and, until you answer, measurement stays cookieless. That failure
                mode is deliberately the quiet one.


                There are **no advertising cookies on this site**: no ad
                network, no remarketing tag, no conversion pixel, no data broker, no
                fingerprinting, and no cookie wall. Rejecting costs you nothing — the whole
                site works exactly the same.

## Strictly necessary storage

These cannot be switched off in the panel, because switching them off would
                break the thing you asked for. They need no consent.


                
                
                    
                        NameWhereWhat it doesLifetime
                    
                    
                        
                            `sumizai.consent`
                            sumizai.com — `localStorage`, not a cookie
                            Remembers the answer you gave the cookie banner, so you are not
                            asked on every page. This is the record of consent itself.
                            Until you clear this site's data, or until we bump the record's
                            version number and ask again.
                        
                        
                            `SUMIZAI_SESSION`
                            app.sumizai.com — cookie
                            Keeps you signed in to the legacy web application.
                            `httpOnly`, so scripts cannot read it, and
                            `SameSite=Lax`.
                            Ends when you sign out or the server expires the session. We do
                            not publish a fixed number here.
                        
                        
                            `XSRF-TOKEN`
                            app.sumizai.com — cookie
                            Cross-site request forgery protection: it lets the app prove a
                            form submission came from its own page. Readable by scripts by
                            design — that is how the token gets into the request.
                            Tied to the session.
                        
                    
                
                
                The two application cookies exist only if you use
                `app.sumizai.com`. Visiting `sumizai.com` never sets
                them.

## Analytics cookies (only after consent)

If you accept analytics, two tools load: **Google Analytics 4**
                (property `G-RKZ7HS09BS`) and **Microsoft Clarity**
                (project `y23mz3osxm`). We use them to see which pages are read,
                which are abandoned, and where a page confuses people. They are the only
                third-party services on this website.


                
                
                    
                        CookieSet byPurposeLifetime (vendor default)
                    
                    
                        
                            `_ga`
                            Google Analytics 4
                            Distinguishes one browser from another, so a person who returns
                            is not counted as a new one.

                            Google Analytics 4
                            Holds the session state for this specific Analytics property.

                            `_clck`
                            Microsoft Clarity
                            Attaches a Clarity identifier to the browser, so several page
                            views belong to one recorded visitor.

                            `_clsk`
                            Microsoft Clarity
                            Joins the page views of a single visit into one session
                            recording.

                            `MUID`
                            Microsoft
                            A Microsoft identifier used across Microsoft's own services;
                            written where Microsoft's domains are reachable from your browser.
                            1 year
                        
                        
                            `CLID`
                            Microsoft Clarity
                            A Clarity identifier marking the first time Clarity saw this
                            browser.
                            1 year
                        
                        
                            `ANONCHK`
                            Microsoft
                            A short-lived Microsoft cookie tied to how `MUID` is
                            handled; Microsoft's own list, linked below, describes it.
                            10 minutes
                        
                    
                
                
                **The names, purposes and lifetimes in that table are the vendors'
                own, as they documented them when this page was written — none of them are
                values we set.** Google and Microsoft can change any of it without
                telling us, and `MUID`, `CLID` and `ANONCHK`
                are set on Microsoft's own domains, not ours, so whether they appear at all
                depends on your browser's third-party cookie settings. Treat the vendors'
                always-current cookie lists, linked further down, as the authority; if you
                want a guarantee rather than a documented default, reject analytics — then
                none of these rows exists.


                Our withdrawal routine also clears `_gid`, `_gat` and
                `SM` if a vendor happens to set them.


                **Where this data goes.** Google and Microsoft run global
                infrastructure, so what their scripts collect may be processed outside the
                European Economic Area, under the safeguards those companies publish for their
                own services — we have no private arrangement with either of them beyond their
                standard terms. We also keep no copy: the statistics stay inside Google
                Analytics and Clarity, for as long as those services retain them, and we cannot
                delete one visitor's history there. Declining analytics, or withdrawing later,
                means the scripts never load and there is nothing to transfer. The
                [Privacy Policy](/legal/privacy.html) sets this out in full.

## What Microsoft Clarity actually records

You deserve to know this in plain words rather than find it in a vendor's
                documentation: **Clarity records your visit as a replayable session**.
                By Microsoft's own description of the product it captures interaction signals —
                pointer movement, scrolling, clicks and taps, window size, the sequence of pages
                — and reconstructs them as a playback of the page you saw, and it aggregates the
                same signals into **heatmaps**. What exactly is captured is
                Microsoft's design, not ours; its documentation, linked below, is the accurate
                and current description.


                So yes: if you accepted analytics, your scrolling on this page can be played
                back. Two things bound it.


                
                    We install Clarity as it comes and leave its default masking of page
                    text and form input in place; we do not use Clarity's APIs to attach an
                    identity, an e-mail address or any custom tag to a session. What that
                    masking does and does not cover is Microsoft's to define, not ours to
                    promise.
                    This is the public marketing site. There is no sign-in on
                    `sumizai.com`, so no account content and no note content can
                    appear in a recording. Your notes never touch this website at all.
                
                Nothing is recorded before you consent, and nothing is recorded after you
                withdraw. What Microsoft does with the data it collects — including where it
                stores it and for how long — is governed by Microsoft's own notice, linked
                below; we do not control it and will not paraphrase it here.

## Google Consent Mode: denied by default

Before any Google script can exist on the page, our consent script sets
                Google Consent Mode v2 defaults. Denied is the starting position, not the
                fallback.


                
                
                    SignalDefaultAfter you accept analytics

                        `ad_storage`deniedstays denied

                The three advertising signals stay denied permanently, because we run no
                advertising and there is nothing for them to enable. Accepting flips exactly one
                switch. Rejecting, or withdrawing later, sets
                `analytics_storage` back to denied.

## Changing or withdrawing your consent

Withdrawing must be as easy as consenting, so it is the same panel, reachable
                from the same place on every page.


                
                    Open **"Cookie settings"** in the footer of any page.
                    Switch **Analytics** on or off.
                    Press **Save choices**.
                
                **Withdrawing does not just stop future tracking — it deletes what was
                already set.** When you turn analytics off, the script immediately expires
                the analytics cookies on this site's domain: `_ga`,
                `_ga_*`, `_gid`, `_gat`, `_clck`,
                `_clsk`, `CLID`, `MUID`, `ANONCHK`
                and `SM`, in their host-only and dot-domain variants.


                What it cannot do is reach cookies stored on Google's or Microsoft's own
                domains — no website can delete another domain's cookies. For those, use your
                browser's controls or the vendors' opt-outs below.


                Withdrawal works forward in time. It does not undo measurements already taken
                and already sent to the vendors, and it does not affect the lawfulness of what
                happened while consent was in force. If you want those earlier records dealt
                with, write to us and read the [Privacy
                Policy](/legal/privacy.html), which sets out your rights of access and erasure.

## Browser controls

Your browser can do more than our panel can, and it applies to every site,
                not just this one. In Chrome, Firefox, Safari or Edge you can block cookies
                entirely, block third-party cookies only, delete stored data for a single site,
                or browse in a private window where everything is discarded when you close it.
                The browser's own help pages are the accurate instructions; they change too
                often for us to reprint them here.


                Two consequences worth knowing:


                
                    Clearing this site's data also clears the `sumizai.consent`
                    record, so the banner comes back and you are asked again. That is the record
                    disappearing, not us ignoring you.
                    Blocking strictly necessary cookies on `app.sumizai.com` will
                    stop you from signing in there. Nothing on `sumizai.com` breaks
                    if you block everything.
                
                Honestly stated: we do **not** currently act on the browser's
                "Do Not Track" header or on a Global Privacy Control signal. The signal we act
                on is the choice you make in the panel, which is why the panel defaults to
                nothing running.

## The applications: desktop and legacy web

**The desktop application sets no cookies at all.** It is a
                native macOS application, and it carries no analytics, no telemetry, no crash
                reporting and no auto-updater — there is no consent banner in it because there
                is nothing to consent to. Your vaults, notes and conversations stay in a local SQLite
                database and in Markdown files in a folder you pick; requests to the AI provider
                you chose go straight from your machine to that provider and never pass through
                any server of ours. We have no way to know you opened it.


                **The legacy web application at `app.sumizai.com`** is
                frozen and separate from the current product. It sets the two strictly necessary
                cookies listed above, `SUMIZAI_SESSION` and `XSRF-TOKEN`,
                and **no analytics cookies** — Google Analytics and Clarity do not
                run there. On its sign-in screen only, and only where the corresponding client
                id is configured, it loads Google's and Apple's sign-in scripts; those providers
                may then set cookies of their own, under their own policies, which we neither
                control nor read.

## The vendors' own notices

These are the vendors' current documents. They are the authoritative source
                for the cookies those vendors set and for what they then do with the data. We do
                not control these pages and cannot promise the links stay valid forever.

## Changes to this policy

The version number and the date at the top of this page are the whole change
                record. We update this document whenever the site's tooling changes — a tool
                added, a tool removed, a cookie renamed by its vendor.


                If a change means the consent you gave no longer matches what would run, we
                do not quietly rely on the old answer. We raise the version number stored in the
                consent record, which invalidates every saved choice, brings the banner back,
                and asks everyone again. Until that new answer arrives, nothing beyond the
                strictly necessary runs.

## Contact

The controller of the personal data that this website's analytics collect —
                and of the account data in the legacy web application — is the operator named
                here, within the meaning of Article 4(7) GDPR. For the desktop application
                there is nothing to control: its notes never reach us. Questions about anything
                on this page, or a request about data already collected, go to a person, not a
                form.

                We publish no telephone number, so e-mail is the channel. Your rights of

                statutory right Polish and EU law gives them; nothing here limits it. This page
