Ouistiti – Y2K Photo Booth is a photobooth for iPhone and iPad: one tap, and four photos become a strip. Optional Host Mode makes it a party's photobooth, set on a tripod for your guests. This page explains, in plain words, what the app does with data. In short: almost everything stays on your device.

The essentials

• Your photos stay on your device. Strips, GIFs, parties, names: everything is kept in the app. I don't have access to any of it.
• A photo only leaves when someone asks. Someone has to tap Share, Save, 4×6 sheet or Print.
• The only exception: purchases. Apple takes the payment. RevenueCat, my service provider, checks your purchases using a randomly generated identifier, without your name. It never receives a photo, a guest's name or a party name.
• No account, no ads, no tracking. I don't sell any data.

Who's responsible

Ouistiti is published by Florian Pichard, an independent developer based in France. I'm the data controller under the GDPR, the European Union's data protection regulation.

Here, “you” means the person using the app; in Host Mode, the party host. “Guests” are the people who step in front of the camera in Host Mode.

What stays on your device

Ouistiti has no server. What you create is saved in the app's own storage, on your iPad or iPhone, and nowhere else:

• The photos. The 4 photos of each strip, taken with the front camera. The app keeps a cropped and color-graded version of them, to make the strip's GIF, to recompose the strip when you edit it, and for the previews in “Your strip”.
• The strips and GIFs, sorted by moment in “Your strips”, or by party in Host Mode. Each strip shows a title (the moment, like “Saturday night”, the one you wrote, or the party name), the names if there are any, the date and, depending on the template, the time. It also keeps the time and time zone it was made in.
• Your booth choices. The template, frame color and format of your next strips, and the title and names written for the day.
• Your Host Mode parties. Party name, names, date, occasion, template, frame color and format, along with the number of strips made.
• Your settings. The saved printer, the guest screen's exit code (never in plain text: only its fingerprint, and the day you chose it), and the Countdown sound, Back to the attract screen and Soft flash options.
• Your purchase status. Whether your Ouistiti Plus subscription is active and until when, and any pending Ask to Buy purchase. The RevenueCat module also keeps your RevenueCat ID and a copy of your purchase history on the device.

The app also reads the device's language, whether Low Power Mode is on and, in Host Mode, the battery level (shown on the guest screen). During a session, and while the Host Mode guest screen is open, it turns the brightness up, then sets it back. Ouistiti doesn't save or send any of this. Only the RevenueCat module sends your preferred languages (see “Purchases”).
