Simple setup
Keep the app. Add OSL.
Use the official app or website. Sign in there. Then choose who OSL should protect.
Sign in with the official service. OSL stays beside it and never receives that password.
Free or Pro
Text is free.
Pro is early access.
Protected text Beta is free on supported connectors. What Pro buys today is early access to new privacy tools as they reach the beta channel. Encrypted image sending Planned, sending other kinds of file Planned and AutoScrub Planned are not in the shipping app yet and are not what you are paying for today.

Pro
$5 / month
The monthly rate shown above is intended pricing. Nothing renews, and OSL never stores your payment details. Checkout is paused until one-month redemption and expiry are implemented.
Pro is an early-access purchase. You are paying to support a product that is still being built, and to get new privacy tools first. You are not buying the finished v1 feature set.
What Pro gives you today
- Everything in Free
- Send protected text on Discord, with no message limit Beta
- New privacy tools first, as they reach the public beta channel
Not in the app yet — you are not paying for these today
- Sending encrypted images, and opening images sent to you
- Sending other kinds of file
- AutoScrub
- View once, expiry and burn
- AI-written cover text
These arrive at v1, and we cannot promise a date. See exactly what works today. Automatic Pro expiry is not implemented, so checkout remains paused.
