Four Burners · Information

Privacy Policy

Last updated: November 10, 2026

The short version

You sign in with your phone number. We keep it encrypted, and look it up by a keyed hash.
If you let the app find friends, it sends your contacts’ phone numbers, never their names. We keep only keyed hashes of them, until you tap Forget my contacts or delete your account.
To turn a video, page or photo into a recipe, we send its text, captions, transcript or photos to our AI provider.
No ads, no selling your information, no tracking you across other apps, and no location.

This policy explains how AlterAspect LLC (“we,” “our,” or “us”) handles information in Four Burners, the iPhone app and fourburners.app (the “Service”).

Information we collect

Your account

Phone number. You sign in with a code sent to your phone number. We store the number encrypted, plus a keyed hash we use to find your account and a masked version (like +1 ••• ••• 0123) to show in the app. We can decrypt it to run the Service. Your country is read from the number.
Your name. The display name you choose.

Friends

Contacts. If you allow access to Contacts, the app sends the phone numbers in your address book to our server over an encrypted connection. It never sends names or any other contact details. Our server turns each number into a keyed hash and keeps only the hash, so friends who join later can be added. The app also keeps its own list of the numbers it sent, on your iPhone. The hashes are kept until you use Settings → Forget my contacts or delete your account. Forgetting your contacts doesn’t remove friends you already have.
Friends and blocks. Who you are friends with and who you’ve blocked.
What friends see. People who have your phone number in their contacts and use Four Burners can see your display name as a suggested friend.

Recipes and cooking

What you import. The links and text you share, and what the app reads from them: a page’s text, a video’s title, description, captions or transcript, photos from a post, and photos you take of recipe cards.
Your recipes, meals and plans. The recipes you save, their photos, your kitchen setup, your meals and cooking plans, and your cooking sessions.
Audio for transcripts. When a video has no captions, the app pulls the audio out on your iPhone and uploads it so it can be transcribed.

Feedback and technical information

Feedback you send. Your message, your device model, iOS and app version, a screenshot if you include one, and up to the last hour of the app’s own logs.
Abuse protection. We use your IP address and a random identifier for this install of the app only to limit sign-in attempts. We keep them only as hashes that expire.
Service logs. Our servers keep short-lived operational logs, which can include your account ID, your country and the links you import.

What happens on your iPhone

The app reads YouTube, TikTok, Instagram and 小红书 posts, and usually web pages, on your iPhone, without signing in to those services. It sends us what it read (text, transcripts, photos or audio), not your accounts on those services. Our server may also fetch a recipe page or its images itself. Invitations to friends are sent from your own Messages app.

How we use information

To sign you in and keep your account secure.
To turn what you share into recipes and to plan and run your cooking.
To suggest friends who are already on Four Burners.
To answer feedback and fix problems.
To prevent abuse and keep the Service running.

Service providers

We share information only with the providers that run parts of the Service for us:

Twilio sends and checks sign-in codes. It receives your phone number.
OpenAI reads what you import and writes it up as a recipe. It receives the text, captions, transcripts and photos of what you import. We ask OpenAI not to store these requests.
fal.ai, running ElevenLabs’ speech model, transcribes the audio of videos without captions.
Cloudflare hosts the Service and stores its data and logs.
Feedback you send goes to the tools we use to track and fix problems, including Slack and GitHub.

We don’t sell or rent your information, we don’t use it for advertising, and we don’t track you across other companies’ apps or websites. The app has no advertising or analytics software and doesn’t use your location. We may disclose information if the law requires it, to protect people’s safety or our rights, or as part of a merger or sale of our business, with notice to you.

Photos and links

Recipe photos, including photos you take of recipe cards, are stored on our servers. They are shown in the app from long, unguessable links that don’t need a sign-in, so anyone you give such a link to can see the photo.

Keeping and deleting your information

We keep your information while you have an account. To delete it, open Settings in Four Burners and tap Delete Account. That deletes your account, your sign-ins, your recipes and their photos, your imports and uploads, your meals and plans, your contact hashes, your friends and blocks (in both directions), and the feedback stored with us.

Some things last a little longer: short-lived service logs, abuse-protection hashes until they expire, and feedback already passed to our support tools. To have that feedback removed, email us.

Your choices and rights

You can turn off Contacts access in iOS Settings at any time, forget the contacts you shared, and delete your account in the app. Depending on where you live, including California, you may have the right to know what we hold about you, get a copy, correct it, or delete it. Email us from any address with the phone number you sign in with; we may ask for details to confirm it’s you. We won’t treat you differently for using these rights.

Security

Information travels over encrypted connections, phone numbers are encrypted at rest, and contacts are kept only as keyed hashes. No system is perfectly secure, but we work to protect your information.

Children

Four Burners isn’t meant for children under 13, and we don’t knowingly collect information from them. If you think a child has given us information, email us and we will delete it.

Changes

We will update this policy when the Service changes, change the date above, and tell you about important changes in the app or by text message.
