Tikwi

Privacy policy

LAST UPDATED · SEPTEMBER 3, 2026

Quick summary, before the details

Tikwi has no server of its own and no user accounts. No email, no password, no sign-up — your phone is the only place your information lives.
Your receipts, products and prices are stored only on your device. No one at Tikwi can see them — not even us.
A receipt photo is sent to OpenAI only to read it and turn it into products and prices — we don't keep a copy anywhere ourselves.
No ads, no third-party analytics. We don't sell or share your data with anyone beyond what's strictly needed to make the app work.

01Who we are

Tikwi is an app for scanning purchase receipts, comparing prices across stores, and keeping a shopping list. It's built by an independent team, with no separate legal entity as of this policy. For any question about your data, write to tikwiapps@gmail.com.

02What data we process, and why

Receipt photos

When you scan a receipt with the camera (or pick a photo already saved in your gallery), that image is sent directly from your phone to OpenAI to read the products, quantities and prices. Tikwi doesn't store that photo on any server of its own — we don't have one — and no copy remains once it's processed, other than whatever copy you already have in your own gallery if that's where it came from.

Barcodes

When you scan a product's barcode, the reading happens on the device itself. If the product isn't already in your catalog, we look up the name on Open Food Facts (a free, public database) using only the barcode — no other data of yours is sent.

Receipts, products, prices and lists

Everything you record in Tikwi (saved receipts, products, prices per store, your shopping list) is stored exclusively in a local database on your device. It never leaves your phone except through your own operating system's backup — see below.

Purchase and subscription (Tikwi Pro)

The purchase itself is handled by Apple's App Store. We use RevenueCat to check that your subscription is active and unlock Pro features — they receive the minimum information needed for that (product identifier, subscription status, an anonymous identifier), never your name, card details, or shopping list data.

System backups

If you have iCloud backup enabled (iOS), Tikwi's database is included there just like any other app data — that's managed by Apple, under its own policy, not by Tikwi.

03Who we share data with

Only these providers, and only for what they need to do:

Provider	What for	What they receive
OpenAI	Reading a receipt photo	The receipt image, nothing else
RevenueCat	Managing the Tikwi Pro subscription	Purchase status, anonymous identifier
Open Food Facts	Suggesting a product name from its barcode	The barcode, nothing else

We don't use advertising networks or third-party analytics or tracking tools. We don't sell data to anyone.

04How long data is kept

On your device, your data is kept until you delete it (product by product, or receipt by receipt) or uninstall the app. Receipt photos sent to OpenAI are governed by their own retention policy, which we don't control — you can read it at openai.com/policies/privacy-policy.

05Your rights, and how to delete your data

You can delete any receipt or product from within the app itself, at any time.
Uninstalling Tikwi completely deletes the local database on your device.
To request access, correction, or deletion of any data we might otherwise hold (e.g. from your correspondence with us), write to tikwiapps@gmail.com.

06Children

Tikwi is not directed at children under 13, and we don't knowingly collect data from children under that age.

07Changes to this policy

If anything changes in how we handle your data, we'll update this same page and the date above. We recommend checking back from time to time.
