Privacy policy

Last updated 14 November 2026

Side by Side is a small research project by Phil Bonhard, made up of an iPhone app and this website. In short: we don't collect your name, email address or Apple ID, we don't track you, and we never sell or share your answers.

The app

What stays on your phone

• The name you type in the first step. It's only used to personalise the journey and never leaves your phone.
• Which journey is which. The app picks this at random when you install it and keeps it on your phone.

What we collect when you send feedback

Nothing is sent until you choose to submit the feedback form at the end. When you do, we receive:

• your answers to the feedback questions, including anything you type in the free-text box (please don't include personal details there)
• the choices you made in the journey, so the app can show how your answers compare with everyone else's
• any accessibility settings you choose to tell us about
• a random ID created when you installed the app, so we don't count the same person twice. It isn't linked to your Apple ID, your name or anything else about you
• some details the app adds automatically: which journey you did first, your iOS version, your iPhone model, your text size setting, whether Reduce Motion is on, and how long you spent on each journey

We use this only to compare the two versions of the journey, for example whether people who use larger text prefer one over the other.

Content the app loads from the internet

Parts of the app load content from servers run by Cloudflare. Like any web server, these receive your IP address and basic details about your device when content loads, and Cloudflare may keep these briefly in its logs for security. We don't use them to identify you.

TestFlight

You install the app through Apple's TestFlight. Apple may share limited information with us, such as crash reports and any screenshots or comments you choose to send through TestFlight. Apple handles this under its own privacy policy.

What we don't do

• No advertising, and no tracking across other apps or websites.
• No analytics or tracking tools built into the app.
• No selling or sharing your answers with anyone.

This website

• No cookies and no analytics.
• The site is hosted by Cloudflare, which handles your IP address to deliver pages and protect against abuse.
• Everything, including the typeface, is served from this site. No other services are involved.

Where your answers are kept, and for how long

Feedback is stored in a database run by Cloudflare. Only Phil can see it. We keep it until the research ends, and delete it no later than 12 months after you send it. Published findings only ever show totals, never individual answers.

The legal part

Phil Bonhard is responsible for this data under UK data protection law (the UK GDPR). We rely on legitimate interests to run this research. Sending feedback is always optional.

Your rights

You can ask to see, correct or delete your answers, or object to us using them. Because we don't know who you are, we may need your help to find your answers, for example roughly when you sent them and which iPhone you used.

If you're unhappy with how we've handled your data, you can complain to the Information Commissioner's Office.

Age

Side by Side is meant for adults. Please don't use it if you're under 18.

Changes

If anything here changes, we'll update this page and the date at the top.
