Effective date: July 5, 2026 · Last updated: October 14, 2026
This Privacy Policy explains how Praxima, Inc. (“Praxima,” “we,” “us”) collects, uses, and shares personal information in connection with Praxima Compass and related features (the “Service”), available at compass.praxima.art and through the Praxima app for iOS.
It applies to everyone whose information we handle through the Service — both account holders and visitors who browse without an account. The Service is offered to users in the United States. Your use of the Service is also governed by our Terms of Use.
Account and identity: your email address (used to sign in, via magic link on the web, or email-and-password in the iOS app) or, if you sign in with Apple or Google, the name and email address your provider shares with us.
Profile:every account has a profile with a display name and username, and optionally a bio, links (such as Instagram or a website), a location you type in, and an avatar — either a photo you upload or a painting chosen from the app’s built-in set (paintings are fetched from Wikimedia Commons).
Content you create:notes on shows (text, photos, and mood tags), which you can publish or keep private; Private Notes, which can include photos and videos from your camera or photo library, wall-text you capture with the camera (text recognition runs on your device), typed text and annotations, voice notes (audio is transcribed on your device; the text syncs to your account and the audio files stay on your device), tags, structured artwork details, and “connections” to venues, shows, and concepts; boards (collections of Private Notes); ratings, including any impression tags you add to a rating; check-ins, gallery walks and attached walk memos, follows, and saved shows, along with the visibility settings you choose for them.
Reports and blocks: if you report content or a person, or block an account, we keep a record so we can act on it.
Communications: anything you send us when you contact customer support.
Both of these are optional, and the Praxima iOS app works fully without them.
Your phone number.The iOS app invites you to add a phone number when you set up your account, and you can add or change one later in Settings. We confirm the number by texting it a one-time code, then store it with your account. We use it to let people who already have your number find your account (see “Finding people you know” below), to help keep fake and duplicate accounts out, and, where phone sign-in is offered, to sign you in. Your number is never shown on your profile or given to other users, and we do not use it for marketing. Message and data rates from your carrier may apply to the verification text.
Your contacts.If you choose to find friends, the iOS app asks for permission to read your address book. With that permission, the app reads only the phone numbers in your contacts — not names, email addresses, photos, or anything else — and sends up to 2,000 of them over an encrypted connection to our servers, where they are compared against the confirmed phone numbers of Praxima accounts. We use those numbers for that one comparison only: we do not store them, log them, or build a record of who is in your address book, and we never contact the people in it. The comparison runs when you choose to find friends during setup, and again when you open the Follow screen while the permission is on (no more than once each time you open the app). You can turn the permission off at any time in your device’s Settings under Privacy & Security → Contacts.
Finding people you know.When a number from someone’s contacts matches the confirmed number on a Praxima account, we show that person the matching account as a suggestion to follow — its display name, username, and avatar, which are already public (Section 3). This means that adding a phone number lets people who already have your number learn that you have a Praxima account. They do not get your number from us, and a private account still approves each follow request. If you would rather not be found this way, skip the phone number, or email privacy@praxima.art and we will remove it from your account.
Usage and device data: pages viewed, features used, usage activities, browser and device types, and similar analytics, collected through our analytics provider, PostHog. In the Praxima iOS app we collect anonymous, aggregated product-usage events (for example, which features are opened) through PostHog to understand how the app is used and improve it. These events are not linked to your identity, are not used for advertising or cross-app tracking, and do not include the contents of your notes, photos, or messages. The app does not include advertising SDKs.
Check-ins:when you check in at an exhibition, we store which exhibition, when, whether the check-in was made manually or generated by the app from a detected visit, and a yes/no flag indicating whether you were physically at the venue — never your coordinates. See Section 4 for exactly how location works.
Recommendations and taste profile:to order the “For You” shelf, the app builds a taste profile from your activity on the Service (saves, check-ins, follows, and ratings) and records which recommended shows were displayed to you and which you opened. We also store the preferences you set yourself: the moods, kinds of art, subjects, artists, and venues you mark as things you’re into or not for you on your Taste profile page, items you remove from it, and your “more like this” / “less like this” feedback on recommendations. These are saved to your account so they carry across your devices and the website. This information is linked to your account and deleted with your account. We use it to rank your recommendations and to show the taste-profile summary on your profile described in Section 3; the preferences you set, the feedback you give, and the record of which recommendations you saw and opened are never shown to anyone.
Error and diagnostic data: technical logs, crash reports, and basic performance diagnostics, collected to keep the Service working and to fix bugs. In the Praxima iOS app this is provided by Sentry. Our error monitoring is configured to scrub personal information (including your IP address) from these reports, and the reports are not linked to your identity.
Local storage: if you build a gallery walk list before signing in, it is stored locally in your browser until you create an account, at which point you can save it to your account. The iOS app similarly stores your notes, drafts, and attached media on your device; when you are signed in, the text and photos of your notes also sync to your account.
We do not knowingly collect Social Security numbers, financial account numbers, government IDs, or precise geolocation. The Service does not process payments.
The Service includes social features. Here is what others can see and how you control it:
Profiles are public by default.Your profile — display name, username, bio, links, avatar, and your follower and following lists and counts — can be viewed by anyone, including visitors without an account. You can switch to a private account; then new follows require your approval and your activity is hidden from non-followers.
Notes on shows are public by default.When you write a note about a show, it is public unless you make it private. A public note — its text, photos, and tags, together with your display name and avatar — appears on that show, in members’ Community feeds, and on your profile, and can be seen by anyone who can view that show, including people browsing without an account. A private note is visible only to you. You can switch a note between public and private, or delete it, at any time; switching takes effect going forward, as described under Audience settings below. Likes and comments you leave on notes are public in the same way, and the reporting and blocking tools in Section 7 apply to notes too.
Private Notes stay private. Notes in your Private Notes collection (behind the lock on your profile) never appear on shows, feeds, or profiles. One becomes visible to others only if you attach it to a walk that you share.
Your taste profile.Your profile shows a summary of your taste: the moods, kinds of art, and subjects that run through the shows you have checked in to and saved; how many shows you have rated; and the city where you check in most. When a signed-in member views your profile, they also see a percentage match between your taste and theirs, calculated on our servers from both members’ ratings and tags. The summary never reveals how you rated any individual show. Someone sees your taste profile only if they are allowed to see your check-ins (your audience settings, private-account setting, and blocks all apply), and its moods, kinds of art, and subjects are drawn only from the check-ins and saved shows that person can already see.
Audience settings.Per-feature controls let you choose who can see your check-ins, ratings, and saved shows: everyone, your followers, or only you. These settings are enforced on our servers, not just in the app. Changing a setting takes effect going forward — content already fetched or shared by link may persist in others’ views or caches. Check-ins generated automatically by the app are kept private regardless of your settings.
Boards can be public or private; public boards are shareable.
Shared walks.Sharing a walk creates a public link. Anyone with the link — no account needed — can see the walk’s name, description, list of stops, your name and avatar, and any notes (“memos”) you attached, including their text, photos, and your identity as their author. Sharing a walk shares its attached notes. Recipients can save a shared walk to their own account; saved copies credit you and link to your profile, and display your memos live — if you unshare or delete the walk, the memos disappear from all saved copies. If someone re-shares a saved copy, it continues to credit you as the original creator.
Images use unlisted links. Images you add to notes are stored at unique, unguessable web addresses. We only reveal those addresses according to your sharing choices, but anyone who has an address can view that image.
In the Praxima iOS app, you may optionally grant when-in-use access to your device location to center the map on nearby galleries, detect which exhibition you are standing at, mark a check-in made at the venue as verified, and power an on-device visit tracker that can offer a “rate your visits” prompt. A separate, optional “always” permission enables geofenced arrival alerts — a notification when you are near a gallery with a show on view — evaluated on your device.
Your precise location is processed only on your device and never transmitted. When you check in at a venue, we store only the fact that you were there (a yes/no verification) and when — never your coordinates. On the web, we may derive an approximate location from your IP address.
We use personal information to:
We do not sell your personal information, and we do not share it for cross-context behavioral advertising.
We share personal information only as follows:
Service providers (processors). We use third-party vendors to run the Service. They process information on our behalf, under contract, and only for the purposes we direct: Supabase (database, authentication, and file storage, in the United States, with row-level security and encrypted backups), Vercel (web hosting), PostHog (product analytics; anonymous feature events only, not linked to your identity, with session replay off), and Sentry (crash and error diagnostics, with personal information and IP addresses scrubbed), and Twilio (delivers the one-time verification text to a phone number you add; it receives that number and the code). In the iOS app, maps are provided by Apple Maps (MapKit), and Apple processes map tiles and queries under its own policy. If you choose Sign in with Apple or Google Sign-In, Apple or Google authenticate you and share with us the name and email address associated with your account. Choosing a painting avatar fetches the image from Wikimedia Commons.
Partner venues (aggregate statistics only).We share aggregated, de-identified attendance statistics (such as the number of verified check-ins at an exhibition) with the venues concerned. These statistics never identify you — venues cannot see who visited.
Other users and the public.Content you make visible through your audience settings, boards, or shared walks, and anything accessible through a share link you generate, is visible to others by design (see Section 3). Information you keep private is not shared this way.
Legal and safety. We may disclose information if required by law or to protect the rights, safety, or property of Praxima, our users, or the public.
Business transfers. If Praxima is involved in a merger, acquisition, financing, or sale of assets, information may be transferred as part of that transaction, subject to this Policy.
You can block accounts (blocking removes the follow relationship in both directions and hides the blocked account from your search results; manage blocked accounts in Settings) and report both people and content, including notes, comments, and walks. Our team reviews reports within 24 hours and may remove content or suspend accounts as described in our Terms of Use. You can also reach us any time at contact@praxima.art.
We use cookies and local storage to keep you signed in, remember preferences, and support analytics. You can control cookies through your browser settings; disabling some cookies may affect how the Service works.
We keep personal information for as long as your account is active and as needed to provide the Service. You can delete your account at any time in the iOS app (Profile → Delete Account) or by emailing privacy@praxima.art. When you delete content or close your account, we delete or deidentify the associated personal information — including your profile, the phone number on your account, follows and follow requests, check-ins, ratings, audience settings, notes and their stored photos, boards, walks and memos, reports, blocks, and notifications — within 30 days, except for limited backups (retained up to 90 days) and information we must keep to comply with this Privacy Policy.
Content you shared may have been saved or copied by others before deletion — for example, a walk another user saved keeps its copied name and description after you delete the original (though attached memos are removed). Aggregated venue statistics (Section 6) are never tied to you and are unaffected by deletion.
We use technical and organizational measures to protect personal information, including encryption in transit, access controls, row-level security on user data, and encrypted backups. No system is perfectly secure, and we cannot guarantee absolute security.
California residents (CCPA/CPRA). You have the right to:
You will not be discriminated against for exercising these rights.
Residents of other states.Several other U.S. states grant comparable rights (such as access, correction, deletion, and portability). If you live in one of these states, you may exercise the rights available to you under your state’s law using the same contact method below.
How to exercise your rights. Email us at privacy@praxima.art. We will verify your request, typically by confirming control of the email associated with your account, and respond within the timeframe required by law. You may use an authorized agent to submit a request on your behalf.
The Service is not directed to children under 13, and we do not knowingly collect personal information from them without parental consent. If you believe a child under 13 has provided us personal information, contact privacy@praxima.art, and we will delete it.
We may update this Policy from time to time. If we make material changes, we will update the “Last updated” date and provide additional notice where appropriate.
