Bytesize
Privacy Policy
Last updated: August 2026
This explains what Bytesize collects, why, and who it's shared with. Written in plain language on purpose —
if anything here is unclear, reach out using the contact info at the bottom.
What we collect
- Account info — your email address and basic profile info, provided by Google when you
sign in. Bytesize never sees or stores your Google password.
- Meal data — when you scan a meal photo, the photo is sent to an AI service to be
analyzed, then discarded — we don't store the photo itself. What we do store is the
AI's text output: estimated calories, nutrients, and ingredients. Meals you log manually are stored the
same way, minus any AI step.
- Chat messages — questions you ask the label chat about a specific meal, and the
replies, so the conversation can continue coherently.
- Payment info — if you subscribe, your card details go directly to Stripe and
never touch our servers. We only receive confirmation that a payment succeeded and your
subscription status.
- Basic usage info — things like how many scans you've used today, needed to enforce plan
limits.
Who we share it with
We don't sell your data. It's shared only with the services that make Bytesize work:
How long we keep it
Your account and meal history stick around for as long as your account exists. You're always in control of
that:
Bytesize has a real, working Delete Account button (in the app, next to your email) that
permanently and immediately removes your account, your meal history, and cancels any active subscription.
There's no waiting period and no need to email anyone to ask.
Security
Passwords are never handled by us at all — sign-in is entirely delegated to Google. Payment details are never
handled by us at all either — that's entirely delegated to Stripe. Reasonable technical measures are used to
protect what we do store, but no system is 100% guaranteed secure, and we can't promise perfect protection
against every possible attack.
Children's privacy
Bytesize isn't directed at children under 13, and we don't knowingly collect information from them. If you
believe a child has provided us information, contact us and we'll remove it.
Changes to this policy
If this policy changes in a meaningful way, we'll update the date at the top of this page.
