Privacy Policy

• Account & sign-in information. If you create an account, Recipe Curveball stores the email address you sign up with. You can sign in with an email and password or with Google sign-in. Email sign-up requires you to confirm your email address before the account is active.
• Saved recipes & recipe notes. When you save a recipe, Recipe Curveball stores the recipe title, ingredients, directions, the source name and web address (when a recipe came from a link), the substitute alternatives you chose, and any personal cooking notes you add to a recipe.
• Allergies & avoidances. The ingredients you add to your Allergies & Avoidances list are saved to your account so Recipe Curveball can flag them and avoid suggesting them as substitutes.
• Kitchen & shopping-list information. Ingredients you add to your shopping list are saved to your account, along with the recipe they came from and whether you have checked them off.
• Recipe links you submit. If you add a recipe by pasting a web link, Recipe Curveball reads the page at that link to find the recipe. If you save that recipe, the source web address may be stored with it.
• Recipe photos you upload. If you add a recipe by photo, the image is sent to Recipe Curveball's servers and to its recipe-reading service so the recipe can be read from it. The photo is used to extract the recipe and is not stored as an image in your account.
• Other information necessary for features. Recipe Curveball may use the recipe details you bring (ingredients, directions) to suggest possible substitutions and to flag ingredients that match your saved avoidances.

Some information is kept only in your web browser and is not sent to your account: the recipe you are currently working on and the substitutes you have chosen are kept in your browser's session storage and are cleared when you close the tab. Marks showing which ingredients you already have are kept in your browser's local storage on your device.

Account data — your saved recipes, notes, allergies & avoidances, and shopping list — is stored with Recipe Curveball's backend provider (Lovable Cloud, powered by Supabase). It is tied to your account so you can reach it again from the website or the app after you sign in. Each account can only read and change its own data.

To turn a photo or link into a recipe and to suggest possible substitutions, Recipe Curveball sends the photo, the page text from a link, and details about the ingredient you want to change to its recipe-reading and suggestion service (the Lovable AI Gateway, which uses a Google Gemini model). This processing is used to return the recipe and the substitution ideas to you.

You can ask Recipe Curveball to delete your account and the data connected to it (such as saved recipes, notes, allergies & avoidances, and your shopping list) at any time. Use the contact form on this page and choose “Delete my data” as the topic. Please include the email address tied to your account so the request can be matched. Deletion requests are handled as soon as reasonably possible.

You can also delete much of your own data directly — for example, by removing saved recipes, avoidances, and shopping-list items within the app, or by clearing your browser's stored data.

Recipe Curveball relies on a small number of services to operate:

• Lovable Cloud (powered by Supabase) — hosts the website and app, provides sign-in, and stores account data such as saved recipes, avoidances, and shopping lists.
• Lovable AI Gateway & Google Gemini — a Google AI model used to read recipes from photos and links and to suggest possible substitutions.
• Google — provides Google sign-in. If you use it, Google handles your sign-in and shares the account information needed to sign you in.
• A web reader service (jina.ai) — used as a fallback to read the text of a recipe page when a direct fetch of your link does not work.
• Google Play — distributes the Android app. Google Play may collect information required to install and update the app, under Google's own policies.

These services may process data as needed to provide their functions, each under their own terms and policies. Data is sent between your device and these services over encrypted (HTTPS) connections.

Recipe Curveball does not sell your personal information. It does not use advertising networks or advertising trackers, and it does not sell or rent your data to third parties.

When something goes wrong, Recipe Curveball's hosting may log technical error information — such as the type of error and the page route involved — to help identify and fix the problem. This is used only for troubleshooting.

If you have a privacy question or want to request deletion of your account or data, use the contact form below. Your message is delivered to Recipe Curveball and reviewed by the account owner; it is not posted publicly.

Recipe Curveball may update this Privacy Policy from time to time. When it does, the updated policy will be posted on this page with a new effective date. Continuing to use Recipe Curveball after a change means you accept the updated policy.
