Privacy Policy · Not My Best Cookbook

This policy explains how the Not My Best Cookbook app for iPhone and iPad, its web version at app.notmybest.cooking, shared recipe pages, and this website at notmybest.cooking (together, “Not My Best Cookbook”) handle your information. Not My Best Cookbook is published by Ossium LLC (“we”, “us”).

The short version

You can use the app without an account. Then your recipes stay on your device and we receive nothing.
If you sign in, we store your account and what you put in your cookbooks (recipes, photos, menu, meals and shopping list) so you can use them on your devices and share them with people you invite.
A cookbook is visible only to its members. A single recipe becomes public only if you turn on its share link, and stops being public when you turn it off.
No ads and no tracking, and we never sell or share your data. The app has no analytics at all. Only this website counts visits, with Cloudflare Web Analytics, which uses no cookies.
You can delete your account and everything only you own at any time, from the app.

Using the app without an account

Signed out, everything you make (recipes, photos, the menu and the shopping list) is stored only on your device. Nothing is sent to us. When you first sign in, it moves into your account.

Your account

You can sign in three ways:

Sign in with Apple. Apple shares a user identifier and an email address with us, and your name if you choose to share it. If you choose “Hide My Email”, we only receive a private relay address. We never see your Apple ID password.
Email link or code. We store your email address and send you a sign-in email.
Email and password. We store your email address. Your password is stored by our sign-in provider as a secure hash; we never see it.

What we store

Data	Why
Email address and account identifier (including your Apple user identifier, if you use Sign in with Apple)	To create your account, sign you in, and match you to cookbook invitations
Your display name	So the members of a shared cookbook know who you are
Your cookbooks: recipes (title, ingredients, steps, times, servings, notes, categories, source link), photos of dishes and steps, favorites, meals, the menu and the shopping list	To keep them in step on your devices and with the people you share a cookbook with
Cookbook members and invitations: who is in each cookbook and their role, and the email address of anyone invited	So invited people can join, and so each person sees only the cookbooks they belong to
Ingredient matches you choose on the Ingredients screen	To estimate nutrition and to search recipes by ingredient
Sign-in records kept by our backend provider, such as the time of sign-in and IP address	To keep accounts secure and prevent abuse

Photos are resized and their location and other metadata removed on your device before they’re uploaded. They are stored privately and shown only to members of the cookbook they belong to.

Sharing

Shared cookbooks. Everyone in a cookbook can see its recipes, photos, menu, meals and shopping list, and its members’ names and email addresses. Editors can change them.
Inviting someone. You enter their email address, which we store with the invitation, and you send them the message yourself from your device. We don’t email them.
Share links. If you turn on a recipe’s share link, anyone with the link can see that recipe’s title, main photo, times, servings, ingredients, steps, notes and source link, at notmybest.cooking. Your name, your other recipes and the rest of your cookbook are not shown. Turning the link off stops it working within a minute.

What stays on your device

Your sign-in session, kept in the iOS Keychain.
A copy of your cookbooks and their photos, so they work offline.
Your settings: units, appearance and whether the screen stays on while cooking.
Cooking timers, scheduled by iOS on your device as alarms or notifications. They never pass through our servers.
Nutrition data for the foods your recipes use, kept so it shows offline.

Signing out removes your cookbooks and session from the device. They stay in your account.

The web version keeps your sign-in session and a few settings (units, light or dark, the cookbook you last opened) in your browser’s local storage. It doesn’t keep a copy of your cookbooks, sets no cookies, and has no analytics. Signing out removes the session.

Importing from websites

When you import a recipe from a website in the app, your device fetches that page directly and reads the recipe on the device. The website sees the request as it would from any browser, and its privacy practices apply to it. We don’t receive the address or the page.

Browsers can’t fetch other websites’ pages, so the web version sends the address to our import service, which fetches the page and returns the recipe. The service doesn’t store the address or the page, though our hosting provider’s request logs may hold them for a few days.

The Recipe Library and nutrition

Searching the Recipe Library and looking up foods for nutrition sends your search words to our database to find matches. We don’t keep a history of your searches, though our database provider’s request logs may hold them for a few days. Nutrition data comes from USDA FoodData Central.

Who processes your data

We use a small number of service providers, only to run the features described above:

Supabase hosts our database and photo storage and handles sign-in, including sending sign-in emails. It stores your account and cookbooks on our behalf. See the Supabase privacy policy.
Apple provides Sign in with Apple and the App Store, and delivers the alarms and notifications your device schedules. See Apple’s privacy policy.
Cloudflare hosts this website, the web version, shared recipe pages and the import service the web version uses, and may process IP addresses to deliver pages and protect against attacks. On this website only, it also provides the visit counts described under Analytics.

These providers may store data in the United States or other countries. We don’t sell your personal information, share it for advertising, or use it to track you across other apps and websites.

Analytics

The app has no analytics. It contains no advertising, no analytics and no tracking SDKs, and nothing about how you use it is measured or sent anywhere.

This website uses Cloudflare Web Analytics to count visits, so we can see which pages people read. It uses no cookies and doesn’t store anything in your browser. It records things like the page you visited, the site that sent you, your browser and device type, your country, and how quickly the page loaded. It doesn’t follow you to other sites, isn’t used for advertising, and isn’t linked to your account. See Cloudflare Web Analytics and the Cloudflare privacy policy.

This website sets no cookies.

Keeping and deleting your data

We keep your data for as long as you have an account. Anything you delete in the app is removed from your cookbook for everyone in it.

To delete your account, tap the account button at the top of Recipes and choose Delete Account. This permanently deletes your account and your profile, and the cookbooks only you are in, with their recipes and photos. A cookbook you share with others passes to another member, with its recipes, so they don’t lose it. If you signed in with Apple, we also revoke the app’s access to your Apple ID. It can’t be undone. Deleted data may remain in our provider’s encrypted backups for a short time until those backups expire.

You can also ask us to delete your account by emailing [email protected] from the address on your account.

Your rights

Depending on where you live, you may have the right to access, correct, export or delete your personal information, or to object to how we use it. You can view, edit and delete your recipes in the app at any time. For anything else, email [email protected] and we’ll respond within 30 days. We won’t treat you differently for using these rights. If you are in the EU or UK, you can also complain to your local data protection authority.

Security

Data travels between the app and our servers over encrypted connections (HTTPS). Database access is restricted so that each person can only read and change the cookbooks they belong to, and photos are stored privately. No system is perfectly secure, but we work to protect your information and keep only what the app needs.

Children

Not My Best Cookbook is not directed to children under 13 (or the minimum age in your country), and we don’t knowingly collect their personal information. If you believe a child has created an account, contact us and we’ll delete it.

Changes to this policy

If we change this policy, we’ll update the date at the top of this page. If a change significantly affects how we use your data, we’ll also let you know in the app before it takes effect.
