Effective date: 6 October 2026
Floorcraft Dance App (“Floorcraft”) is a West Coast Swing practice-coordination app published by Antigrav Design Studio LLC (“we”, “us”). This policy explains what the app collects, why, who else sees it, and what you can do about it. It covers the Floorcraft mobile app, the Floorcraft web pages that open from a shared practice link (at go.floorcraftapp.com), and floorcraftapp.com. We do not sell your information and we do not share it with advertisers. There is no advertising in the app today (see Advertising below). The app does send crash reports and basic usage analytics, described below; neither is tied to your name, email or account.
When you create an account and use Floorcraft, you provide:
Your name and email address, used to sign you in and to identify you to other people in a practice.
A profile photo, if you choose to add one. Optional.
Your home city, which you type or select. Used to sort and filter practices by distance.
Your role preferences per practice: Lead, Follow, or either.
A Venmo handle or payment link, if you host a practice that costs money. Optional, and visible to people attending that practice.
If you sign in to the app with your mobile number, you provide that number, which we confirm with a code, and you may add a recovery email address so you can get back into your account if you lose the number.
If you RSVP from a link on the web
A practice link can open a Floorcraft web page where you can RSVP without installing the app. Your RSVP creates a Floorcraft account that you sign in to with your mobile number. To RSVP there, you provide:
The role you choose (Lead, Follow, or either), which is how you RSVP.
Your name, so the host and the other people in the practice know who is coming.
Your mobile phone number, which we confirm with a code. It lets the host of a practice you join message you, and lets you come back to your RSVP from any phone. It must be a US number.
A photo, if you choose to add one. Optional.
Your phone number is never shown to the host or to anyone else in the practice. We use it for two things only: to send you a sign-in code or to sign you in to the app, and to deliver up to 2 messages per practice date from the host of a practice you RSVPed to. We do not use it for marketing, and we do not sell or share it. Reply STOP to any text to stop them; your RSVP stays. Your phone number is also how you sign back in: enter it on any practice page and we text you a code, so you can see or cancel your RSVPs from any phone. No mobile information will be shared with third parties or affiliates for marketing or promotional purposes. Text messaging opt-in data and consent are not shared with any third party.
RSVPs — which practices you have joined, which role you hold, and whether you are on a waitlist.
Comments and reactions you post on a practice page. These are visible to everyone who can see that practice.
Messages you send to or receive from a practice host. Only the two people in a conversation can read it. A message is checked automatically for banned words before it is sent. If one of you reports a message, that message alone is reviewed by our moderation process, which includes an automated review tool.
Practices you create, if you host: title, description, date and time, location, cost, and any links you add.
Your notification preferences, per practice and as your saved default.
A push notification token for each device you sign in on, so we can send the notifications you have turned on.
A history of the notifications we have sent you, so you can see them again in the app.
Whether a host has recorded you as having paid for a practice that costs money, and any practice credits a host has granted you.
Whether a host has removed or blocked you from a practice they run.
Crash reports and usage analytics
The app sends two kinds of technical information. Neither is tied to your name, your email or your account.
Crash reports. When the app crashes or hits an error, it sends what went wrong in the code, the screen you were on, your device model, your operating system and the app version. These go to Sentry.
Usage analytics. Which screens are opened and which main actions are taken (for example, that an RSVP was made or a practice was created), with the app version and device type. These go to PostHog, on its United States servers. It does not record what you type, what is on your screen, or which practice or person was involved, and there is no session recording.
Both use a random identifier created when the app is installed. It is not linked to your account, it is replaced if you reinstall the app, and we do not use your device’s advertising identifier. Both services receive your device’s IP address as part of any internet connection; we set them not to store it and not to use it to estimate your location. We use this information only to find and fix problems and to understand which parts of the app are used.
We are naming these because people reasonably assume otherwise:
We do not collect your device’s location. The app never asks for location permission and cannot read your GPS. Distance is measured from the home city you typed.
We do not currently use advertising or cross-app tracking. Currently there is no advertising SDK in the app, we do not use your device’s advertising identifier, and we do not share information with data brokers. Crash reports and usage analytics are described above; they go only to the two providers named there.
We do not process payments and never see payment details. If a practice costs money, you pay the host directly, outside of the app — the app only shows the host’s payment link. We never collect card numbers or bank details.
We do not read your contacts, your calendar, your photo library at large, or your microphone.
We do not collect biometric data. Face ID, Touch ID and Android biometrics are checked by your device and never reach us. We do not analyse faces in photos.
Photos — only when you tap to choose a profile photo or a practice image. We receive the image you pick, and nothing else from your library.
Camera — only when you tap Take Photo to set a profile photo. We receive the photo you take, and nothing else from the camera.
Notifications — only if you agree, and only to send the notifications you have turned on. You can turn them off at any time in your device settings or in the app.
Calendar — only when you tap to add a practice to your calendar. The app writes that one event. It does not read your calendar and no calendar information is sent to us.
To run the app, and for nothing else: to sign you in, to show your name and photo to other people in practices you join, to seat people in roles and manage waitlists, to notify you about practices you have opted into, to let hosts manage their own practices, to review reports of content that may break our community guidelines, to find and fix crashes, to understand which parts of the app are used, and to keep the service working and secure.
Other people using the app. Your name, photo, and role are visible to other people in a practice you join. Comments you post are visible to everyone who can see that practice. Messages are visible only to you and the other person in the conversation. A host of a practice you join can see that you have joined and can record whether you have paid. If you RSVP from a link on the web, your name, photo and role are shown in the same way. Your phone number is never shown to anyone.

Cloudflare Turnstile
Checking that an RSVP from a link comes from a person, not a bot. It runs invisibly and processes your IP address and browser details. See Cloudflare’s Turnstile Privacy Addendum: cloudflare.com/turnstile-privacy-policy
We may also disclose information if the law requires it, or to protect the rights and safety of our users or ourselves. We do not sell your personal information, and we do not share it with third parties for their own marketing.
We keep your account information for as long as your account exists. Practices, RSVPs and comments are kept as part of the record of the group, so that other people’s history stays intact. When you ask us to delete your account we remove your profile information as described below.
Messages are kept for as long as the conversation exists. If you delete a message you sent, it is removed. Your notification history is kept for 90 days, then deleted.
One anonymous record is kept after an account is deleted. When you delete your account we keep the reason you chose and the date, together with a small, deliberately vague sketch of the account: a broad description of the area you were in, roughly how active you were, roughly how often you invited people, roughly how long you had been here, whether you ever hosted a practice, roughly how recently you had last used the app, and whether you were on an iPhone or an Android phone. Each is deliberately vague — “top-quarter percentile”, “over a year” — and never specific. It carries nothing that identifies you, no link of any kind back to your account, and the area is widened until it covers at least 25 people. We keep it only to notice patterns across many departures — for example, a lot of active people leaving at once — and we read it in aggregate. It cannot be traced back to anyone, nor can it be deleted on request.
We keep no database backups, so no backup copy of your information outlives a deletion. When your account is deleted, it is deleted — there is no stored copy sitting behind it that quietly keeps your data for another few weeks.
If you RSVP from a link on the web, your name, photo and role are kept as part of that practice’s record, like any other RSVP. Your phone number is kept for as long as your account exists. Cancelling your RSVP removes your name and photo from that practice; deleting your account removes the number and every RSVP made with it.
We keep a record of your text-message consent and any STOP request for four years, as the law expects, even after your number is removed. It is used only to show that we had your permission.
Crash reports are kept for up to 90 days and usage analytics for up to one year. Because neither is linked to your account, they cannot be looked up or deleted by account; they are removed on those schedules.
Advertising
Floorcraft does not show ads today and has no advertising software in it. We plan to add advertising in a future version. Before any advertising reaches the app, we will update this policy to say what it collects and who receives it, change the effective date, tell you in the app, and ask for your permission wherever the law or your device requires it.
See or correct your information — your photo, home city and notification preferences can all be edited in the app at any time. Your name is set when you create your account; if it needs correcting, email support@floorcraftapp.com. Turn off notifications — per practice, per category, or entirely, in the app or in your device settings. Delete your account — you can do this yourself in the app, from your profile settings. Your profile, your photo and your RSVPs are removed straight away. Comments you have posted stay where you wrote them, with your name and photo taken off, so that other people’s conversations are not rewritten. Messages you have sent stay in the other person’s conversation with your name and photo taken off, in the same way. If you host a practice, it passes to another member so that nobody loses their place; if there is no one to pass it to, it is removed along with your account. One anonymous record is kept, described above. You can also email support@floorcraftapp.com if you would rather we did it for you. Cancel an RSVP or remove your phone number — if you RSVPed from a link on the web, cancel from the practice page after signing in with your number. To delete your phone number and every RSVP made with it, delete your account, or email support@floorcraftapp.com with the number and we will do it. Reply STOP to any text to stop texts without deleting anything.
Access to your information is restricted at the database level, so that people can only read and change the records they are entitled to. Data is encrypted in transit. No system is perfectly secure, and we cannot guarantee absolute security. If a security incident affects your information, we will tell you as the law requires, by email or in the app.
Floorcraft is for adults. It is not directed to anyone under 18, and we do not knowingly collect information from anyone under 18. If you believe someone under 18 has an account or an RSVP, contact us at the address below and we will delete it.
This policy and your use of Floorcraft are governed by the laws of the State of Colorado, United States, without regard to its conflict-of-laws rules. Floorcraft is offered in the United States. It is not directed to, or offered in, the European Union or the United Kingdom.
If we change this policy we will update the effective date at the top, and for significant changes we will tell you in the app.
