Privacy policy

Last updated October 28, 2026

Osler Press is run by The Plain Works Co., Ltd., 901-C32, 126 Wolbong-ro, Seobuk-gu, Cheonan-si, Chungcheongnam-do 31166, Republic of Korea ("we"). This policy says what we keep and why.

What we keep

• Account: your email address and a salted hash of your password.
• Preps: the tooth, the date and the numbers of each prep you score. Your photos stay on your device: the scorer runs in your browser and the photo is never uploaded.
• Share cards: when you share a prep, the card image and its numbers. Share cards never show your email or name.
• Payments: Paddle (Paddle.com Market Ltd) is the merchant of record and handles your card and billing details. We receive the plan, the amount and the dates.
• Usage: page views and feature events through PostHog, to see which pages help.

What we never do

We do not sell your data and do not send it to any AI service. No AI runs in Osler Press.

Your rights

Delete any prep from your rep log at any time. To delete your account and all its data, or to get a copy, write to hello@oslerpress.com; we answer within 30 days.
