Privacy

Privacy Policy.

This policy covers the DigitalKnife apps for iOS and Android (phones and tablets), and the Web Workspace and website at digitalknife.io.

Last updated: 16 October 2026

In short

We don't use cookies. Not in the app, not on our website.

  • We only process what the app needs to work, and what you choose to share.
  • We don't sell your data.
  • We don't show ads, and we don't track you across other apps or websites.
  • Anonymous usage statistics are collected only if you tap "Yes, allow". You can change that anytime in Settings.
  • You can delete your account and your data yourself, in the app.

Who is responsible

The data controller responsible for your personal data is:
Catalin Cucu, Franz-Linher-Straße 81, 5020 Salzburg, Austria.

What we process, and why

Your account

If you create an account, we process your email address and password (handled securely by Google Firebase Authentication; we never see your password), or your Sign in with Apple / Sign in with Google login, with the name and email they share with us (with Apple you can hide your real email). Why: to give you an account, keep your data safe and sync it across your phone, tablet and the Web Workspace. Legal basis: contract (Art. 6(1)(b) GDPR).

Account emails

When you create an account with email and password, we send you a link to confirm your address, and up to 3 reminders if it isn't confirmed. We need this to run your account, so it doesn't depend on newsletter consent. We use Brevo to send them. Legal basis: contract.

What you create in the app

Recipes, food-cost calculations, ingredient prices and suppliers, daily orders and order history, Walk-In entries, notes, reminders, to-dos, allergen settings and your business details (restaurant name, your name and title, currency). When you are signed in, these are stored with your account on Google Firebase, so they sync and are backed up. We don't look at your content and don't use it for anything else. We only access it if you ask us for help, or if the law requires it. Legal basis: contract.

Your setup answers

The answers you give during setup (for example your role, experience, region, currency and favourite ingredient). They are used to set up the app for you and to understand who our users are. If you have an account, they are saved with it. Legal basis: contract and our legitimate interest in improving DigitalKnife (Art. 6(1)(f)).

Free trial and subscriptions

Payments are handled entirely by the store you buy through (Apple App Store or Google Play); we never see your payment details. Our subscription service RevenueCat receives an anonymous ID (after sign-in: your account ID) and your purchase information, to unlock the plan you bought. We store your plan, trial status and expiry date with your account. Legal basis: contract and legal obligations (tax and accounting).

AI features

When you use AI Recipe Search, import a recipe from a file, scan a recipe page or detect allergens, the text, document text or photo you send goes to our server in Frankfurt and from there to Anthropic, which generates the result. We don't send your name, email or account details to Anthropic. We don't store your text, photos or results on our server. We only keep a short technical log (account ID, which feature, time, language) for 90 days, to prevent misuse. Results are saved only where you choose to save them. Please don't include personal information about others in photos or text you send. Legal basis: contract.

Calorie Calculator

The ingredient you search for is sent to the public USDA FoodData Central database. Nothing that identifies you is sent.

Usage statistics, only with your consent

If you tap "Yes, allow", we use Google Firebase Analytics to see how the app is used: which screens and tools are opened, setup steps, plan screens, device type, operating system version, app version and approximate country. It uses a random app ID and is not linked to your name, email or account. Advertising features are switched off, and Google Signals is off. If you tap "No thanks", or don't choose, nothing is collected. You can change your choice anytime in Settings → Share anonymous usage data. Legal basis: your consent (Art. 6(1)(a) GDPR, § 165 TKG 2021).

Crash reports

If the app crashes, Google Firebase Crashlytics sends us a crash report: what went wrong, on which screen, device type, operating system version and a random installation ID. It is not linked to your account. We use it only to find and fix errors. Legal basis: our legitimate interest in a stable and secure app (Art. 6(1)(f)).

Support, feedback and reviews

If you contact us or send feedback, we process your email, your name, your message, topic, language, account ID, and the page, browser and device you sent it from, to answer you. To prevent spam, we also keep a scrambled (hashed) version of your IP address if you are not signed in. If you submit a review, your name, role, restaurant and review text are shown publicly once we approve it. Legal basis: contract / your request; consent for public reviews.

Newsletter

Only if you tick "Product news" or "Offers". We use Brevo to send emails. You can unsubscribe in every email or in the app. We keep a record of your consent, as the law requires. Legal basis: consent.

Notifications

Reminders and timer alerts are scheduled on your phone. They can show reminder or note titles, and the start of a note, on your Lock Screen. You can turn them off in your phone's settings.

Stored on your phone

Your settings, recent AI searches and their results (kept 30 days after last use), and a copy of your data for offline use. Saved meals from older app versions that were kept in your private iCloud are moved into your account. Signing out or deleting your account clears this from the phone.

Our website and Web Workspace

The Web Workspace uses the same account and data as the app. On our website we count page visits with Plausible Analytics, which uses no cookies, collects no personal data and stores everything in the EU. We don't set any cookies, so there is no cookie banner. Your browser only stores what the site needs to work: your sign-in, an offline copy of your data, and your language and theme. Our fonts are hosted on our own server, so loading the site sends nothing to Google. Legal basis: our legitimate interest in knowing which pages are useful.

How long we keep it

  • Account and content: until you delete them or your account.
  • AI technical log: 90 days.
  • Crash reports: 90 days.
  • Usage statistics: 14 months.
  • Subscription and purchase records: as long as tax law requires.
  • Newsletter consent record: as long as needed to prove your consent.

Deleting your account

Profile → Account → Delete account. This deletes your account and everything stored with it on our servers: your content, setup answers, AI log, support requests, feedback, reviews, your newsletter contact at Brevo and your record at RevenueCat. It also clears your data from this phone. Important: deleting your account does not cancel a subscription. Cancel it in your Apple ID or Google Play subscription settings. The store keeps its own purchase records. You can also delete your account on the web at digitalknife.io/delete-account, or by emailing us.

Your rights

You can ask us for a copy of your data, to correct or delete it, to restrict or object to processing, and for data portability (Art. 15–21 GDPR). You can withdraw consent anytime; this doesn't affect what was processed before. Contact: smartchef@digitalknife.io. You can also complain to the Austrian Data Protection Authority (Datenschutzbehörde, www.dsb.gv.at).

Children

DigitalKnife is made for professional and adult home cooks and is not directed at children under 16.

Changes

If we change how we use data (for example, if we ever add ads for free users), we will update this policy, tell you in the app, and ask for your consent where required.
