Privacy

Brow Tine is made by Double Tap Software, LLC, in New Hampshire. This page covers both the app and this website.

Location

Brow Tine is a map you use in the woods, so location is the heart of it. The app asks for it in two separate steps, and it is worth being precise about the difference.

• While you are using the app. Your position draws the blue dot on the map, centres the map on you, and tells you which deer unit and which weapon restriction apply to the ground under your feet. This stays on your phone.
• In the background, when the app is closed or not in use. This is a separate permission and the app asks for it separately, with an explanation, at the moment a feature needs it. Exactly two features do:
  • Recording a walk. So the track keeps drawing with the phone in your pocket and the screen off. The recorded walk is yours and stays on your phone unless you are signed in, in which case it syncs to your account so you can see it on your other devices.
  • Sharing your position with your hunting party. So standers and drivers can still see each other when the phone is away. See the next section.

Background location is optional. If you say no, both features still work, they just pause whenever the app is not in front, and the app tells you so rather than quietly recording nothing. You can change your mind at any time in your phone's settings, and you can revoke location entirely. The free map, the public land layers and the weapon restriction and deer unit layers never require an account.

Sharing with your hunting party

A party is a crew you create or join with a code. When you go live, your phone sends your position to the people in that party and nobody else. What goes up is your coordinates, the accuracy of the fix, and, when the phone can tell, your heading and speed, labelled with your display name.

• Live positions are never written to our database. They pass through a live connection to the members of your party and are gone. We do not keep a history of where you have been.
• Going live is a deliberate act, it is limited to the one party you chose, and it stops when you stop sharing or leave.
• What we do store is the durable crew itself: the party name, its join code, who is in it, each member's map colour, and when they joined or left.

Camera and photos

• The camera is used for two things: photographing sign and dropping a pin at that spot, and scanning a QR code to accept a waypoint from someone else's phone. The app does not record video and does not use your microphone. It does not request microphone access at all.
• Photos you attach to a pin are stored on your phone, and, if you are signed in, backed up to your account so they survive a lost phone and appear on your other devices. They are stored under your own user ID and a signed-in session can only ever reach its own.
• Saving a copy to your phone's camera roll is off by default and is a setting you turn on. The app reads nothing else from your photo library.

What you save in the app

Pins, trail cameras and recorded walks are yours. Without an account they stay on your phone. Signed in, they back up to your account so you can move to a new phone, and so a broken phone does not take your season with it. If you create a share link for a waypoint, the snapshot behind that link expires on its own, and it never includes your photos.

Your account

• Your email address, and a display name if you set one, so your party knows which dot is you. A display name is free text and does not have to be your real name.
• Your password is never stored. We keep a salted, peppered PBKDF2 hash of it, and the pepper is not in the database.
• Sign-in tokens are stored as hashes on our side, so a database leak cannot be replayed as you, and the token on your phone lives in the operating system's secure storage. We record when a session was created, last used and revoked, so you can be signed out.
• We log failed sign-in and password-reset attempts, with the email tried and the IP address, purely to rate-limit them.

Paying

Subscriptions are handled on this website by Stripe, and card details go to Stripe, never to us. We keep only what tells us whether your access is current: the subscription's status, which plan it is, when the period ends, and a Stripe customer reference. The app never takes payment and contains no purchase screen.

What we never do

• No advertising, no ad identifiers, no data brokers.
• No analytics or tracking SDKs, in the app or on this site. We do not build a profile of you.
• We never sell or rent your information, and we do not share it with anyone except the services listed below that are required to run the product.
• No contacts, no call or message data, no microphone, no health or fitness data, no advertising ID.

Other services the app talks to

A map has to fetch things. These services see the request, which means your IP address and, for map and weather requests, roughly where you are looking. None of them are given your account, your name or your email.

• Cloudflare, which runs our database, our servers and our storage, and delivers our map tiles and aerial imagery.
• The U.S. Geological Survey for the topographic and satellite basemap.
• The National Weather Service for wind and weather.
• The U.S. Census Bureau and NH GRANIT at the University of New Hampshire for address search, which only happens when you search for an address.
• Stripe for subscriptions, and Microsoft 365 for the mail sent to us through the support form.

Deleting your account

There is a delete button in the app, under your account, and it is a real deletion rather than a flag. It removes your user record, every sign-in session and pending token, your synced pins, trail cameras and walks, any share links you made, and your photos and recorded tracks from our storage.

Two honest caveats. Billing records that Stripe and we are required to keep for accounting survive the account, and the anonymous rate-limiting log ages out on its own. Anything you have already shared with your hunting party, or sent to someone as a waypoint, is on their phone and we cannot reach into it.

Children

Brow Tine is a tool for licensed hunters and is not directed at children. We do not knowingly collect information from anyone under 13.

This website

Separately from the app, this site does two things with your data: if you put your name and email in the early-access form, we store them so we can email you when Brow Tine is ready to test, and if you write to us through the support form, we store your name, email and message so we can reply.

• The name and email you typed, and, on the support form, your message.
• The date you signed up, your browser's user-agent string, and the country Cloudflare reports for your request, used to spot abuse of the form, nothing else.

It is stored in a Cloudflare D1 database. To be taken off, send us a note through the support form and we will delete your row. No questions, no retention period.

Changes, and how to reach us

If this policy changes in a way that affects what we collect, we will update the date at the top and say what changed. Questions, or a request to see or remove your data, go through the support form, which is our contact channel.
