Privacy Policy

Effective November 9, 2026

Tahor is built to need as little of your information as possible. There are no accounts, no ads, no tracking or analytics, and nothing is sold.

What stays on your phone

Your history, clean list, verifications, kosher settings, added products and app settings are saved only in your browser's storage on your device. Tahor's server never receives your history, list, verifications or settings. Erase all Tahor data in Settings, or clearing your browser's site data, deletes them.

Photos you take are read on your device. The image is not uploaded.

What is sent to look things up

To find a product, Tahor sends the barcode, NDC or search words to public databases: Open Food Facts, the NIH Dietary Supplement Label Database, openFDA, and the National Library of Medicine (RxNorm). USDA FoodData Central and DailyMed lookups pass through Tahor's own server. These services receive the request and your device's internet address, as any website does, and handle it under their own privacy policies. Pasted or photographed ingredient text is checked on your device.

One exception: when a barcode isn't found and you add the ingredients yourself, Tahor sends that barcode, the product name and the ingredient text to Tahor's server, so the product can be added for everyone. Nothing personal is included.

The app also loads fonts from Google Fonts and code libraries from unpkg and jsDelivr, which receive your internet address when they load.

Reports you choose to send

If you tap Report a problem, Tahor's server stores the report: the report type, your note, the product's name, brand, barcode, data source and ingredient text, the verdict, and the app version. Reports do not include your name, email or location. To limit abuse, the server keeps a one-way scrambled form of your internet address, used only to count reports per hour. Like most web hosts, the hosting provider may keep standard server logs.

Sharing

Share links and share images are created on your device and go only where you send them.

Children

Tahor is meant for general audiences and does not knowingly collect personal information from anyone.

Changes and questions

This policy may be updated as Tahor grows, and the date above will show when. Questions can be sent with Report a problem in the app.
