1. What we use
| Name | Type | Purpose | Lifetime |
|---|---|---|---|
| Session | Cookie / browser storage | Keeps you signed in between page loads | Until sign-out or session expiry |
| Session refresh | Cookie / browser storage | Issues a new session when the old one expires, so you are not signed out constantly | As configured by the system |
| Language | Browser storage | Remembers whether you chose English or Vietnamese | Until you clear browser data |
| Interface preferences | Browser storage | Remembers panel state, zoom level and similar editor preferences | Until you clear browser data |
| Local drafts | Browser storage | Holds what you are editing when the connection drops, so no work is lost | Until synced or cleared |
All of these are strictly necessary: turn them off and sign-in and the editor stop working properly.
2. What we do not use
- No Google Analytics, no Tag Manager, no other behavioural measurement tool.
- No advertising pixels from Facebook, Google or any ad network.
- No third-party cookies that follow you between websites.
- No heatmaps, no session recording.
This describes the actual state of the code as of the last-updated date at the top of this page, not a general promise.
3. Embedded third-party content
If you embed video or other content from another service in a presentation (YouTube, for example), that service may set its own cookies when a viewer plays it. That is outside our control and governed by their policy.
Signing in with Google takes you to a Google page, where Google's own cookies apply.
4. How to control them
Every browser lets you inspect, delete and block cookies. If you block cookies for mosra.app you will not be able to sign in — that is a direct consequence, not a bug.
Clearing browser data for mosra.app signs you out and discards saved interface preferences.
5. If we add measurement
When we do switch on an analytics tool, this page will be updated first, and you will get a consent prompt that lets you decline while keeping full use of the Service. Declining will not cost you a feature.
