LockDraw is an Android drawing app published by Korshunov Maksim. This policy applies to LockDraw on Google Play (com.afirglent.lockdra).
Last updated: November 11, 2026.
LockDraw stores personal drawings, previews and preferences on your device. The widget and wallpaper use a local copy. When you export or share a drawing, the file goes to the destination you choose. Android may back up personal drawings if system backup is enabled. Room credentials, the installation key and pending shared edits are kept outside Android backup.
When you create or join a room, the room server receives your display name, room and participant identifiers, session credentials, and shared drawing data such as strokes, text, stickers and backgrounds. The server stores room data and synchronizes the shared drawing with participants. Use invitation codes only with people you want to invite. The invitation code lasts up to 24 hours. A session lasts up to 30 days and may be renewed. Expiring a code or session does not delete the shared drawing.
When joining, the app sends a random installation key. The server stores a separate hash for each room. It uses that hash to enforce room blocks, including when a new invitation is issued. The hash associated with an existing block may stay with the active room after a guest deletes their data so the block continues to work.
When you report a participant, the server records the room and participant identifiers, the reason, and the time. A drawing report also includes the current synchronized drawing. Moderators with access to the service use those records to review reports and record decisions. Technical connection and request information may be processed to deliver the service and limit abuse.
Fly.io hosts the room service and processes the connection and room data needed to provide it. The active room database is stored on an encrypted volume in Amsterdam, the Netherlands. The app connects over HTTPS. The service uses the IP address to limit how often clients can send requests, with request counters kept in memory.
Room data stays in active storage until the room is deleted. Invitation and session expiry only end the associated access. Fly.io stores encrypted daily volume snapshots in the United States. The snapshots are configured to expire after five days. A snapshot made before a deletion may still contain the deleted data until it expires. Report and moderation records are kept separately for reviewing reports and enforcing room rules. They do not have an automatic expiration date. You can contact us about access to or deletion of separately retained data. Fly.io information about hosting and backups
Open the shared drawing and tap Room details. The owner can choose Delete room to remove the shared drawing, participants, invitations and sessions from active storage. A guest can choose Delete my data to remove their room profile, session data and the edits the server can attribute to them. Other participants can continue to use the room after a guest removes their own data.
LockDraw saves a personal copy before sending either deletion request. The app confirms deletion when the server has processed it. Deleting a room leaves a minimal room identifier to prevent an old request from recreating it. Moderation records and earlier server backups are stored separately from active room data. Copies that participants saved or exported are controlled on their own devices. Contact us for questions about data retained separately or help locating the deletion controls.
The initial public release has advertising disabled. It does not include the CAS.AI SDK or display ads. If advertising is enabled in a later release, this policy will be updated to describe the advertising SDKs and the choices available in the app.
In builds with Firebase configured, crash diagnostics can include crash details and app or device information. Optional usage statistics are controlled separately in Settings and are off by default. Drawings and drawing text are not included in LockDraw usage events. Google Privacy Policy
