Rephotograph never uploads your photos. It has no account, no analytics and no server of its own. A few things go to Apple so it can draw maps and name places, and every one of them is listed on this page.

What stays on your iPhone

Rephotograph keeps a record of the photos you have been back to. For each return it notes when you took it, where you stood and the place's name, how far you were from the original spot, and how the new photo lines up with the old one. That record is a database inside the app on this iPhone. It does not sync to your other devices, and Sacrifice Golf, LLC cannot see it.

The app also keeps:

• Photos you have taken but not yet saved, so they survive iOS closing the app. Each is deleted when you save or discard it, they are left out of your backups, and any left after two weeks are cleared the next time you open the camera.
• The outlines it draws from your originals, so the camera opens quickly. iOS can clear these at any time.
• Copies of what you share, made for the share sheet in a temporary folder that iOS clears from time to time. A series video is replaced each time you make another.
• For each photo you have moved with Fix Location, where it was and which way it faced before, so Restore can put it back, and for each photo you have given a location with Add Location, that it had none, so Remove Location can take it off again.
• Which pictures in your library it saved there itself, when you save a series as photos, so it does not offer them back to you as photos to retake. Only their library identifiers are kept, not the pictures.
• A few settings, such as the map's style and where you last left it, and the photo size you chose on the camera.

iOS includes the app's data in your iPhone's backups, as it does for any app, apart from the unsaved photos, the outlines and the sharing copies above. Deleting Rephotograph deletes all of it. The photos it saved stay in your library until you delete them there, and locations it changed stay as they are in Photos.

What Rephotograph asks for, and why

Rephotograph asks for three permissions. You can change any of them later in Settings, then Apps, then Rephotograph.

Photos

The permission prompt says it directly: Rephotograph reads your photo library to load the original photo and extract its GPS location, direction, and lens data. It reads your library to put your photos on its map, lists your albums, shared albums included, so you can browse them, and reads each original for where it was taken, which way the camera faced, the camera, lens and settings that took it, how the camera was tilted, and how you cropped it in Photos. All of that is read on your iPhone.

It changes your library only when you ask it to:

• Saving a rephotograph adds the new photo to your library, and puts it and the original in an album called Rephotograph.
• Fix Location changes a photo's location in Photos, and its direction if you turn it, and Restore puts back what Photos had before. Add Location gives a location to a photo that has none, and Remove Location takes it off again.
• Saving a series as photos adds new pictures. They carry no location. The file holds only a note saying Rephotograph made them, so that if one is shared back to Rephotograph it can say so.
• If you choose Save Image or Save Video in the share sheet, iOS saves that file to your library.

It never deletes anything from your library. If you allow only selected photos, Rephotograph works with those, and saves new photos without the album.

Location

Only while you are using the app, never in the background. Rephotograph shows you on its maps, works out how far you are from where the original was taken and in which direction, and turns the dot green when you are standing there. It asks for precise location because that spot is measured in metres; with approximate location the dot cannot turn green.

When you take a rephotograph, where you stood and which way you faced are written into the photo, as the Camera app does. In Fix Location and Add Location, the location arrow puts the pin where you are standing, and Add Location starts there when it can. If you save the pin there, where you stood becomes that photo's location in Photos. Rephotograph does not send your location anywhere itself. The maps described below download the area around you in order to draw it.

Camera

For the live viewfinder you line the original up in, and to take the photo. Rephotograph takes still photos only. It does not record video or sound and does not use the microphone. While you line up a shot it looks at up to four black-and-white copies of the live picture a second, to check which of the original's lines the scene still has. Those copies are never stored or sent.

Compass and level

The compass comes with the location permission. The level reads the iPhone's motion sensors, which iOS does not ask permission for. Both are used live, on screen. The direction you faced is saved into each rephotograph you take.

Starting from the Photos app

When you share a photo from the Photos app to Rephotograph, iOS hands Rephotograph a copy of it. Rephotograph reads the time it was taken, its size and its location from that copy, uses them to find the same photo in your library, and opens that photo's page. It also checks the copy for the note iOS writes into a screenshot, or the one Rephotograph writes into a series photo, and if it finds one it says so instead of opening. All of this happens on your iPhone. The copy is not kept, nothing is sent anywhere, and this part of the app asks for no permission of its own.

What leaves your iPhone

Rephotograph has no server, so nothing it does reaches Sacrifice Golf, LLC unless you write to us, visit this website, or let Apple pass on the reports described below. This is the complete list of what leaves the phone. The first four go to Apple, under Apple's own privacy policy.

Maps

Rephotograph's maps are Apple Maps. To draw one, your iPhone downloads map and satellite imagery from Apple for the area on screen, which is usually the area around you or around your photos.

Place names

To name the place a photo was taken, Rephotograph sends Apple that photo's coordinates. For a stack of photos on the map, it sends the middle of the stack. It sends the coordinates and nothing else: not the photo, and not its date.

Apple Maps and Photos

Tapping the green distance pill on a photo opens Apple Maps with directions to where it was taken. Rephotograph hands Maps that spot and its place name, and Maps works out the route from where you are. The Open Photos button on a full-screen photo opens the Photos app and passes it nothing.

iCloud Photos

If you use iCloud Photos, your library is already in your own iCloud account. When Rephotograph needs a photo that is not on the iPhone, Photos downloads it from iCloud. When Rephotograph saves a photo, adds to its album or changes a location, Photos syncs that change to iCloud, as it does any change you make in Photos. Rephotograph never uploads a photo itself.

Email to support

Email support, in Rephotograph's About screen, opens your own mail app with a message to support@sacrificegolf.com. Under it, Rephotograph writes the app's version, the iOS version and your iPhone's model, so the first reply does not have to ask. You can read, change or delete all of it, and nothing is sent unless you send it. If you do, Sacrifice Golf, LLC receives your email and uses it only to answer you.

Links in the About screen

Privacy Policy opens this page in your web browser, and Rate Rephotograph opens Rephotograph in the App Store. Rephotograph passes them nothing but the address. This website is hosted by Squarespace, and your browser visits it as it would any other site.

What you share

Share sends what you choose to the app you choose. A rephotograph shared as a photo file is the file itself, so, like a photo from the Camera app, it carries where it was taken and which way the camera faced. The Then & Now card, a series video and a series' photos carry no location, and no place name unless you type one into the caption.

Crash reports, if you share them

If you have turned on Share With App Developers in your iPhone's settings, Apple may pass crash reports and usage statistics for Rephotograph to Sacrifice Golf, LLC. That is a setting of your iPhone, not of the app. You will find it in Settings, then Privacy & Security, then Analytics & Improvements. If you test a beta of Rephotograph through TestFlight, Apple shares with Sacrifice Golf, LLC what TestFlight's own terms describe: your name and email address if you were invited by email, how you use the beta, its crash reports, and any feedback you send.

What Rephotograph never does

• No account. There is nothing to sign in to.
• No analytics, no advertising and no tracking. The app's privacy manifest declares no tracking, because there is none.
• No third-party code. Rephotograph is built only from Apple's own frameworks.
• It never uploads your photos, and never deletes anything from your library.
• It never reads your clipboard. Copy #RephotographApp, and Copy Address on Email support, only put text on it.
• Nothing is sold, and nothing is shared beyond what this page lists.

Children

Rephotograph is not directed at children. It has no accounts and collects nothing from anyone, of any age.

Changes

When this policy changes, the date at the top of this page changes with it. If a future version of Rephotograph ever sends something new off the iPhone, it gets its own section here first.
