Privacy policy

Publisher and scope

This policy describes the Android app Kadreno, application ID com.bapps.stickerstudio. Its publisher is Mandelshtam Dmitri Konstantinovich, IP (Individual Entrepreneur), trading as BApps Development. For privacy and app questions, email bappsdevelopment@gmail.com.

Files and information you choose

The app receives photos, videos and backup archives you select with Android’s system picker, or photos and videos you explicitly share with it from another app. It does not scan your gallery in the background or request access to your entire media library. It does not use the camera or microphone.

A private copy of a selected source stays inside the app so you can edit it later. Your gallery original is not overwritten. The copy can retain the original file’s metadata, including location metadata if present, and any audio track in a source video. Finished stickers have no sound.

The app stores your projects, editing recipes, masks, text, pack names, the author name you enter, emoji, settings, previews, prepared output files and local export status records. It uses these to edit, preview, save, export, back up and restore your work.

Processing on your device

Photo, video-frame and mask processing runs on your device. The bundled model separates a person from the background; it is not used to identify the person. Automatic masks can make mistakes.

The app has no account registration, developer backend, advertising, purchases, analytics or remote crash-reporting SDK. This version does not request Android’s INTERNET permission and does not send your media, projects, device identifiers or usage statistics to the publisher. It checks whether supported messengers are available to offer export options; this result is not sent to the publisher.

Export to messengers

When you choose to export, the app gives the selected messenger access to your prepared stickers and the information required for the pack, such as emoji and, depending on the destination, its name, author and cover. Telegram receives access to the prepared files through Android file links (URIs).

When you prepare a WhatsApp pack, the app saves a separate copy of its final files and pack details. A read-only Android provider makes these prepared files, the pack name, author, emoji and cover available to the authorized WhatsApp client. These copies remain available after preparation, including when you delete the editable project, so the pack can keep working. Remove a prepared WhatsApp pack separately in the app’s settings; doing so may stop that pack working in the messenger.

The messenger controls its own further uploads, storage, synchronization and sharing under its rules and your actions. It must be installed and may require its own account. Kadreno does not receive that account’s password or conversations.

Saved files and manual backups

You choose where to save PNG, GIF, ZIP and backup files through Android’s system document dialog. The selected file provider may be local or cloud-based and may upload or synchronize files under its own rules.

A manual backup is an unencrypted ZIP containing your source media, projects and settings. Original metadata and source-video audio can therefore be included. The backup excludes prepared WhatsApp provider files and generated previews. Checksums detect corruption; they do not hide the contents or establish that an archive came from a trusted person. Anyone who obtains a backup can read it. Choose its storage carefully.

Storage and protection

Working data and prepared outputs are stored in Android’s private app storage. The app does not add its own encryption to projects and source files. Device protection depends on Android and your device settings. Copies saved through the system dialog or passed to other apps may be stored outside this private area.

Android automatic cloud backup is disabled for this app, and its Android backup rules exclude app data from device-to-device transfer. These settings do not control copies you create yourself or independent features of the device manufacturer. The operating system, app store and other services may process their own data independently of Kadreno.

Keeping and deleting your work

• Editable projects and private source copies remain until you delete them or remove the app’s local data. Deleting them does not delete your gallery originals.
• Prepared WhatsApp packs are retained separately, including previously prepared versions. Delete them with the separate prepared-pack action in settings.
• Clearing temporary files removes cache and regenerable Telegram/file export copies. It keeps editable projects, source copies and prepared WhatsApp packs.
• Uninstalling the app or clearing its data in Android removes its local data. Files, backups and messenger copies already saved elsewhere must be deleted separately there. Deleting the app does not delete those copies. The app does not promise physical, irreversible erasure of device storage.

Up to 100 recent export records remain locally until replaced by newer records or the app’s data is cleared. They contain pack references, destination, progress, status or error, times and private file references.

Contacting the publisher

If you email us, we receive the sender address, message and attachments you choose to send and use them to respond to your request. Email is separate from the app’s local processing and is handled by the email services involved. Avoid sending unnecessary private media. Removing the app does not remove email correspondence. Send app or privacy questions to bappsdevelopment@gmail.com.

This policy page and changes

This page contains no scripts, analytics or forms. Its hosting service may process technical requests under its own rules. We will update this policy when the app’s data handling changes and show the updated date here. This policy is available in English, Russian, German, Spanish and French.
