1. Who we are

KNOWE is made by KNOWE Studios, Inc., a Delaware corporation ("Knowe", "we", "us"). This policy covers the KNOWE iPhone app, the two extensions bundled with it (the KNOWE Safari extension and the KNOWE share-sheet extension), and the website at knowe.app (including knowe.design, which points to the same site). Together we call these the "Service".

Knowe is a styling companion. You show us your taste by swiping, saving and trying looks on, and we style you for your moments, sometimes with a human stylist. Doing that well means handling personal information, including photos of you. This page says exactly what happens to it.

2. The short version

• We collect what you give us to style you: your email, name, birthdate, sizes, the notes and photos you choose to add, and the looks you love, pass, save and try on.
• Your full-body try-on photo stays on your phone. It's sent to OpenAI's image model only when you run a try-on, to generate the result, and it isn't used to recognise or identify you.
• We don't sell your information and we don't share it for cross-context advertising. There are no ad networks in the app and no tracking across other companies' apps or websites.
• A small number of service providers process data for us (hosting, image generation, product search, push notifications, product analytics and crash reporting). Every one of them is named in section 6.
• You can delete your account from your Profile at any time. That removes your data and your photos from our systems.
• KNOWE is for adults. You must be 18 or older to have an account.

3. What we collect

Almost everything below is optional. The app works with an email and a password; the rest makes styling better and you choose how much to add.

Account and profile

• Sign-in details: your email address and password. We store only a salted hash of the password, never the password itself.
• Profile: your name, username, gender selection (HER or HIM), birthdate, city, sizes for tops, bottoms and shoes, body notes you write for fit, your budget range, favourite brands, artists and shows, and a profile photo if you add one.
• Notification preferences and which editorial drops you've asked to hear about.

Photos and images

• Full-body try-on photo: the photo you add so virtual try-on can show looks on you. It's stored on your phone (and in a shared container on the phone so the extensions can use it). It isn't uploaded to our storage; it's sent to the image model each time you run a try-on, with the occasion you type for that try-on, if any. See section 5.
• Try-on results: the generated images of you wearing a look, which include your likeness. They're saved in a folder tied to your account in our storage so they appear in your LOOK BOOK. In app versions that offer a background choice, choosing one processes the result again to cut out the figure and place it on the background.
• Capsule photos: photos of pieces you own that you add to your CAPSULE.
• Photos you submit to identify a piece or find similar pieces. To run an image search these are placed at a link the search provider can read.

Taste and saves

• Every love and pass in a deck, with the image and moment it belonged to, how long you took to decide and where in the deck it sat.
• Saves to CAPSULE, SHORTLIST and LOOK BOOK, with any notes, categories, prices and product links you attach.
• MY SIGNATURE: a written taste profile (summary, brands, colours, descriptors) we derive from the above.

Styling bookings and messages

• When you book a stylist: the occasion and its type, the date, the service tier and delivery speed, your budget, the location you enter (name, map coordinates and place reference), what you're picturing, moment notes, pieces you'd like styled around, and friends you tag.
• The looks drafted for your booking, and messages between you and your stylist in the session thread.

Friends, invites and sharing

• Friend requests and friendships, and the usernames you search for.
• Calendar moments you create and the people you invite. If you invite someone by phone number, we store that number with the invite so the link can be redeemed.
• Occasions from your iPhone calendar, only if you turn the calendar sync on in MOMENTS or Profile: the title, date, time and place of upcoming events on the calendars you choose, and the name of the calendar each is on, for the next three months. We never read the guest list, notes or attachments, and we never write to your calendar. Turn the sync off in Profile and the imported occasions are deleted.
• Whether each saved item in LOOK BOOK and SHORTLIST is shared with friends, and a public shortlist link if you create one by tapping SHARE. Anyone with that link can see your name and the items in the shortlist.

Voice

• If you describe a piece by voice, the app records your microphone only while you hold to speak and transcribes it. The transcript is used to fill in the piece's details.

The Safari extension

• When you tap Save to KNOWE on a product page, the extension reads that page's title, image and address and hands them to the app. It can also run a try-on from Safari using your saved photo.
• When you send something to KNOWE from another app's share sheet (a link from Chrome or a retailer app, a pin from Pinterest, a post or a photo from Instagram or Photos), the share extension receives only what you shared: the address and title, or the photo and its caption. It can also run a try-on on it using your saved photo. It reads nothing else from that app, and it only runs when you pick KNOWE in the share sheet.
• The extension shows a small tab on pages so you can save from anywhere, but it sends nothing until you act. We don't collect your browsing history.

Device and usage

• A push notification token for your device, and whether it's a production or test build.
• In-app events such as screens viewed, taps on products and outbound links, app opens, and which features were switched on for you, tied to your account so we can see what's working. These go to our own database and to PostHog, our analytics provider (section 6).
• With each of those events, the details of your phone and the app: app version and build, iPhone model, iOS version, screen size, language, time zone, whether you're on Wi-Fi or cellular, and whether the build came from TestFlight. Your IP address reaches PostHog with each request, as it does with any server. PostHog discards it instead of storing it with the event, and doesn't turn it into a location. We never send your email or name to PostHog.
• A record of each request to our image and language models (which feature, when, an estimated cost) tied to your account, so we can control spend and stop abuse.
• A few steps that happen on our servers rather than in the app, which our servers send to PostHog (section 6), tied to your account so we can see what's working: whether each try-on finished or why it didn't, with the model and its estimated cost from the record above, and the steps of a styling session you book (booked, looks drafted, a look approved, a change of status) with its tier. These carry no phone or app details, and never your photos, the occasion, notes, budget or location, or anything you typed.
• Issue reports you file from the app, with the screen you were on.
• If the app crashes or hits an error, a crash or error report: what failed and where in the app's code, a short list of what the app did just before (for example, which request failed and its status code), and the phone and app details above, tied to your account. A crash report is sent the next time you open the app. These go to PostHog (section 6). They don't include photos or what's on screen, and never your email or name.

The website and the waiting list

• If you join the list at knowe.app: your email, your three quiz answers (moment, style lean, spend), and any referral code or campaign tags on the link you used.
• If you reserve a founding membership: Stripe handles the payment. We receive and store a Stripe customer reference, the checkout session reference and the amount. We never see your card number.

Support

• Anything you send to support@knowe.app, and reports you file about content or members in the app.

4. Why we use it

• To run the Service: sign you in, build your taste profile, show you looks, generate try-ons, keep your saves, deliver bookings and messages, send the notifications you've asked for, and drain your Safari saves into your shortlist.
• To style you well: sizes, body notes, budget and taste signals shape what we and your stylist recommend.
• To keep KNOWE safe and honest: enforce our Terms, review reports, detect abuse, and control the cost of the AI features.
• To understand and improve the product: aggregate usage of features and flows, and crash and error reports so we can fix what breaks. We don't build advertising profiles.
• To talk to you: account emails such as password resets, replies to support, and, if you joined the list, your invitation.
• To meet legal obligations and protect our rights.

If you're in the EEA, the UK or Switzerland, our legal bases are: performance of our contract with you (running the Service); your consent (photos of you, voice, notifications, your calendar and optional profile fields), which you can withdraw at any time; our legitimate interests (keeping the Service secure, improving it and controlling its cost), balanced against your rights; and our legal obligations.

5. Photos, likeness and try-on

This section exists because photos of your body deserve plain language.

• What try-on does. When you tap TRY ON, the app sends your full-body photo, the images of the pieces you chose (up to 12 at once) and the occasion you typed, if any, to OpenAI's image model in one request. The model returns a new image of you wearing those pieces, in a scene that suits the occasion or, if you left it blank, the pieces.
• Generation, not identification. The photo is used to generate an image. We don't use facial recognition, we don't create or store a face template, faceprint or any measurement that could identify you, and we don't compare your photo against anyone else's. To our knowledge the model providers don't either; their terms are linked in section 6.
• Where the photo lives. On your phone, in the app's private storage, plus a smaller copy in the app's shared container so the extensions can run a try-on without opening the app. Replacing or removing your photo in Profile removes both copies. We don't keep a copy of the source photo on our servers.
• Results are kept for you. Generated try-on images are stored in our storage, tied to your account, so they appear in your LOOK BOOK. Delete a look to remove it; delete your account to remove all of them.
• Backgrounds. In app versions that offer a background choice, if you change the background of a result, the generated image is sent to remove.bg to cut out the figure, then composited on the background you chose.
• Only you. Add photos of yourself, or of someone who has clearly agreed. Our Terms don't allow try-ons of other people without their consent.
• Your consent, and biometric privacy laws. Before your first try-on photo the app shows a consent screen that says what is captured, who processes it, where it lives and how to delete it, and records when you agreed. You can withdraw that consent at any time by removing your photo or deleting your account. We don't sell, lease, trade or otherwise profit from photos of you, and we don't create a face template, faceprint or any other biometric identifier from them. Where a law (for example in Illinois, Texas or Washington) treats photos processed by an image model as biometric data, that consent screen, this section and the retention rules in section 7 are our written policy for it: photos and generated images are kept only until you delete them or your account.

6. Who we share it with

We share personal information only in the ways below. We don't sell it, and we don't share it for cross-context behavioural advertising.

Service providers

These companies process data on our instructions to run the Service. Each receives only what the feature needs.

When you tap SHOP THIS or open a product or article, you leave for the retailer's or publisher's site. Their privacy policy applies there. We record that you tapped the link.

Your stylist

When you book, the stylist working on your session sees your booking details, your messages, and the profile fields that help them style you (name, sizes, body notes, budget, taste profile, and your profile photo if you added one). Stylists agree to use that information only for your session.

Friends and the public

Your username and name are visible to members who search for you. What friends see of your LOOK BOOK and SHORTLIST is governed by the per-item sharing you choose in MY EDIT. A public shortlist link is visible to anyone who has it.

Legal and business

We may disclose information to comply with law, a court order or a lawful request; to enforce our Terms; to protect the safety of members or the public; or to a successor in a merger, acquisition or sale of assets, in which case this policy continues to apply to the transferred data.

7. How long we keep it

• Photos and generated images: until you delete the item or delete your account. Your full-body photo lives on your phone and is removed when you replace it, remove it, or delete the app.
• Account, profile, taste, saves, bookings and messages: for as long as you have an account.
• Usage events and AI request records: up to 24 months in identifiable form in our database, then de-identified (the link to your account is removed) or deleted. The copy of the usage events, crash reports and error reports that PostHog holds is kept for 1 year. When you delete your account, our records are de-identified straight away; the copy at PostHog keeps your account id, which no longer points to anyone once the account is gone, together with the device details described in section 3, and expires on that 1-year schedule.
• Waiting-list entries: until we've sent invitations for the launch, or earlier if you ask us to remove yours. Founding reservation records are kept as long as needed for your membership and for tax and accounting law.
• Support email and reports: up to 2 years after the matter is closed, so we can follow up and show how a report was handled. Issue reports you file from the app are deleted with your account.
• Backups: our database provider keeps rolling backups for a short period (7 days). Deleted data drops out of backups on that schedule.
• Service providers: the AI providers above may retain requests briefly for abuse monitoring under their own terms (from about an hour at remove.bg to 30 days at OpenAI) and, on the tiers we use, don't use your content to train their models.

8. Deleting your account and your choices

Delete your account

In the app, open your Profile, scroll to the bottom and tap Delete account, then confirm. This permanently deletes your account, your profile, your taste data, your saves, your bookings and messages, your friendships and invites, and the images stored under your account (try-on results and capsule photos). It can't be undone. If you can't get into the app, email support@knowe.app from the address on the account and we'll delete it for you within 30 days.

Other choices

• Photos: replace or remove your try-on photo in Profile. Delete any try-on result or capsule photo from MY EDIT.
• Permissions: camera, photo library, microphone, speech recognition, calendar and notifications are each optional and can be changed any time in iPhone Settings.
• Sharing: choose item by item what friends can see, in MY EDIT. A public shortlist link exists only if you've tapped SHARE on your SHORTLIST; to disable a link you've sent out, email support@knowe.app.
• Notifications: choose which drops you hear about in Profile, or turn them off in Settings.
• Email: account emails (like password resets) are required to run the Service. Anything else has an unsubscribe link.
• Tracking: the app doesn't track you across other companies' apps and websites, so it never asks for App Tracking Transparency permission.

9. Children

KNOWE is for adults. You must be 18 or older to create an account. We ask for your birthdate when you set up your profile and don't allow accounts below that age. We don't knowingly collect personal information from anyone under 18, and never from a child under 13. If you believe someone under 18 has an account, email support@knowe.app and we'll delete it.

10. Security

Data travels over encrypted connections (TLS). Your data in our database is protected by per-row access rules so your account can only read its own rows. Passwords are hashed. Access to production systems is limited to the people who need it. No system is perfectly secure; if we learn of a breach affecting your information we'll notify you as the law requires.

11. Where your data lives

We're based in the United States and our systems and most providers are there (see the table in section 6; remove.bg is in Austria, Searlo's servers are in France and Open-Meteo is in Switzerland). If you use KNOWE from outside the US, your information is transferred to and processed in the US, where privacy law may differ from your country's. If you use KNOWE from the EEA, the UK or Switzerland, we rely on the European Commission's Standard Contractual Clauses (and the EU-US Data Privacy Framework where a provider is certified under it) for these transfers. Email us for a copy of the clauses.

12. Your rights

Depending on where you live you may have the right to access, correct, delete or receive a copy of your personal information, to object to or restrict certain processing, and to withdraw consent. You can do most of this yourself in the app (edit your profile, delete items, delete your account). For anything else, email support@knowe.app. We'll verify the request using the email on your account and respond within the time the law allows (45 days under US state privacy laws, extendable once by a further 45 days; one month under the GDPR and UK GDPR, extendable by two months for complex requests). We won't treat you differently for exercising your rights.

California residents. The categories we collect are listed in section 3 (identifiers, characteristics such as birthdate and gender, commercial information such as saves and reservations, visual information, audio when you use voice, internet activity in the app, geolocation you enter for bookings, and inferences such as your taste profile). We disclose them to the service providers in section 6 for business purposes. We don't sell personal information and don't share it for cross-context behavioural advertising, and we haven't in the past 12 months. You may designate an authorised agent; we'll ask them for proof. We use sensitive personal information, such as photos of you, only to provide the features you ask for, so the right to limit its use doesn't apply. Because we don't sell or share personal information, we don't offer a "Do Not Sell or Share My Personal Information" link.

EEA, UK and Switzerland. KNOWE is offered in the United States. If you use it from the EEA, the UK or Switzerland, the controller of your personal information is KNOWE Studios, Inc., 2021 Fillmore St, PMB 2419, San Francisco, CA 94115; we haven't appointed a local representative. Email support@knowe.app to exercise your rights, and you can also lodge a complaint with your data protection authority (in the UK, the Information Commissioner's Office).

13. Changes to this policy

When we change this policy we'll update the effective date at the top. If a change materially affects how we handle photos or other personal information, we'll tell you in the app or by email before it takes effect.
