PRIVACY POLICY
Your food diary
is your business.
Welcome to Crumb! We're really glad you're here. We know privacy policies are usually about as fun to read as a phone book (remember those?), so we're going to try to keep this light, honest, and actually readable. This policy is part of our Terms of Service, which you accept by using Crumb.
LAST UPDATED · JULY 6, 2026
What We Collect
We collect the food you tell us about (pizza, salads, that questionable gas station burrito), whether you type it, say it, or snap a photo of it. We also collect your email address and the basics we need to personalize your targets: your age, height, weight, and activity level. Add some basic usage and crash data (covered in the Cookies & Tracking section below), and that's pretty much it.
Voice logging is transcribed by Apple's speech recognition, which runs on your phone or, in some cases, on Apple's servers (per Apple's privacy terms). Either way, we only ever receive the text, never the recording. Meal photos are sent securely to our AI service to identify the food, and that's all we use them for.
We're not interested in your browsing history or what you're doing on other apps. Payments? Those are handled entirely by Apple, so we never see your card details.
If you let us use your location for restaurant meals, we only use it to get accurate nutrition info nearby. That's it.
The AI Thing
When you tell us what you ate, we send that to trusted AI services to estimate the nutrition info: one that looks up nutrition data, and one that identifies food in photos. Here's the important part: we only send the description or photo of the food itself, never your name, email, or anything else that identifies you. To them, it's just an anonymous sandwich.
Apple Health
If you turn on Apple Health sync (it's off until you flip the toggle in Settings), Crumb writes your logged meals to Apple Health: calories, protein, carbs, fat, fiber, and sugar. Edit or delete a meal in Crumb and we update or remove it in Health too. If you only grant permission for some of those, we only write the ones you allowed.
We never read your Health data. Crumb doesn't ask for read access at all, so we can't see your workouts, your weight, your heart rate, or anything another app put there. The only thing Crumb ever looks up in Apple Health is the meal entries it wrote itself, so it can keep them updated or delete them when you do.
Data you sync to Apple Health is stored on your device under Apple's HealthKit rules. We never use it for advertising, and we never share it with anyone.
How We Protect Your Data
We use Firebase to store your data securely. Think of it like a really good vault, but for your meal history. Your data is encrypted both in transit (when it's traveling) and at rest (when it's sitting on servers). We take security seriously, even if we don't take ourselves too seriously.
One honest note: no system on the internet is 100% secure, and anyone who tells you otherwise is selling something. What we can promise is that we follow industry-standard practices, and if anything ever did go wrong, we'd tell you promptly instead of hoping you wouldn't notice.
Wherever you live, your data is currently stored and processed on servers in the United States. If that ever changes, we'll update this policy.
What We DON'T Do
We don't sell your data.
We don't share your data with advertisers.
We don't judge your 2am snack choices.
We don't look at your food diary unless you specifically ask us for help.
Your nutrition journey is yours, and we respect that.
Cookies & Tracking
We don't use cookies (ironic for a food app, we know), and we don't track you across the internet.
Full transparency: inside the app, we use Firebase Analytics and Crashlytics. That means we receive basic usage data (which features get used) and crash reports (so we can fix what broke). This data is about your device and the app, not about you or your food, and we never use it for advertising.
Sharing Your Data
The only time we'd share your data is if legally required (like a court order), or if you explicitly tell us to (like exporting your data). Otherwise, your food diary stays private. We wouldn't share our meal history either.
One honest caveat: if Crumb is ever acquired by or merged with another company, your data would transfer as part of that, and we'd notify you before it happens, so you could request an export or delete your data first if you wanted to.
Your Rights
You can delete your account anytime.
Want a copy of your data? Email us and we'll send you an export. (An in-app export button is on the roadmap, but for now a human handles it, usually within a few days.)
You can ask us questions anytime.
When you delete your account, your data is deleted from our systems within 30 days. Residual copies in backups clear out shortly after that, and then it's gone for good.
Depending on where you live (like the EU, UK, or California), you may have additional legal rights over your data: access, correction, portability, and more. Email us and we'll honor them, no forms or lawyers required. You also always have the right to complain to your local data protection authority, though we'd appreciate the chance to fix things first.
You're in control here. We built this app to help you, not trap you.
Kids
Crumb is not intended for anyone under 13. If you're under 13 and reading this, impressive reading skills! But please check with your parents before using our app.
Changes to This Policy
If we change this policy, we'll update the date at the top, and if the changes are significant we'll let you know in the app. We won't make any sneaky changes. We're not that kind of company.
The Bottom Line
We built Crumb because we wanted a simple way to track nutrition without the hassle. We respect your privacy because we'd want the same respect. We keep your data secure, we don't sell it, and we don't do anything shady with it.
That's it. That's the whole policy.
