SDM (SoftTech Download Manager)
Legal Information, Privacy Policy, Terms & Licenses
🔒 Summary: Zero Telemetry, 100% On-Device Execution
SDM is built with a strict privacy-first architecture. We do not track you, we do not collect your URLs or files, there are no user accounts, and zero analytical telemetry is sent to SoftTech Service or any third-party servers.
This Privacy Policy explains how SDM (SoftTech Download Manager) ("the application", "we", "us") handles information when you use our Android application.
1. Information Handled Locally On Your Device
All data created or entered in SDM remains exclusively on your local Android device storage within the app's protected sandbox and database:
- Download Links & Magnet URIs: URLs, magnet links, or torrent file paths entered manually or intercepted from your clipboard are stored locally in the app's Room database to manage active, paused, and completed download queues.
- File Metadata & State: Download progress, chunk verification checksums, download speeds, file names, file sizes, and custom organizational tags.
- App Preferences: Your configured settings such as download speed limits, Wi-Fi only rules, charger rules, custom storage directory paths, and schedule timers.
We have no access to this data. It is never uploaded, synced, or backed up to any cloud servers operated by SoftTech Service.
2. What We Do NOT Collect
- No Personal Identifiable Information (PII): We do not ask for or collect names, email addresses, phone numbers, contacts, or passwords.
- No Tracking or Analytics SDKs: SDM contains zero analytical trackers (such as Google Analytics, Firebase, Facebook SDK, AppsFlyer, etc.).
- No Advertising Identifiers: SDM contains zero advertising frameworks or ad trackers.
- No Browsing History or Search Logs: We do not log or monitor websites you visit or files you download.
3. Network Communication & BitTorrent Swarms
SDM requires network access solely to fulfill user-requested file downloads and BitTorrent swarm operations:
- HTTP/HTTPS Direct Downloads: The app connects directly to the server specified in the URL you provide to fetch byte ranges of your file.
- BitTorrent Peer-to-Peer (P2P) Swarms: When initiating torrent or magnet downloads, the underlying C++ libtorrent engine connects to tracker servers, DHT (Distributed Hash Table) nodes, and peer swarms. In accordance with the fundamental architecture of the BitTorrent protocol, your IP address is visible to other swarm peers sharing the same pieces of the torrent.
4. Storage & SAF (Storage Access Framework)
SDM uses Android's modern Storage Access Framework (SAF). You choose the specific folder on internal memory or external MicroSD storage where downloaded files will be written. SDM only accesses the directory tree you explicitly authorize.
5. Data Retention & User Deletion Rights
Because all data is stored strictly on your device:
- You can delete individual downloads or torrent sessions along with their downloaded files directly from the SDM UI.
- Clearing the app's storage in Android Settings or uninstalling the app permanently removes all local task records and configurations.
6. Children's Privacy
SDM does not knowingly collect or solicit any information from children under the age of 13. The app is a general-purpose download tool that operates entirely offline/client-side without user accounts.

1. Acceptance of Terms
By installing, running, or using SDM (SoftTech Download Manager), you agree to be bound by these Terms & Conditions. If you do not agree to these terms, do not install or use the application.
2. Lawful & Responsible Use
SDM is a high-speed utility application designed to facilitate network transfers via HTTP, HTTPS, and peer-to-peer BitTorrent protocols.
- User Responsibility: You are solely responsible for all content, URLs, and torrents you download or share using SDM.
- Copyright & Intellectual Property: You agree to use SDM only to download content that you own, have licensed, or have legal permission to access in accordance with applicable laws in your jurisdiction.
- No Illegal Activities: You agree not to use the application for any unlawful purposes, including but not limited to the unauthorized distribution of copyrighted material, malware, or malicious code.
3. BitTorrent P2P Protocol Disclosure
You acknowledge and understand that BitTorrent is a decentralized peer-to-peer protocol. When downloading or seeding torrents:
- Your device participates in a distributed swarm and may upload pieces of downloaded files to other swarm members.
- Your IP address is broadcast to other peers in the swarm and DHT network as necessary to establish peer connections.
- SoftTech Service does not host, curate, control, or monitor any torrent files, magnet links, or download servers accessed by users.
4. Disclaimer of Warranties ("As Is")
SDM IS PROVIDED "AS IS" AND "AS AVAILABLE", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT.
SoftTech Service does not warrant that the application will be uninterrupted, error-free, completely immune to network timeouts, or compatible with every web server or torrent swarm.
5. Limitation of Liability
IN NO EVENT SHALL SOFTTECH SERVICE, ITS DEVELOPERS, OR CONTRIBUTORS BE LIABLE FOR ANY DIRECT, INDIRECT, INCIDENTAL, SPECIAL, EXEMPLARY, OR CONSEQUENTIAL DAMAGES (INCLUDING LOSS OF DATA, DEVICE DAMAGE, NETWORK OVERAGE CHARGES, OR INTERRUPTION OF BUSINESS) ARISING OUT OF THE USE OR INABILITY TO USE THIS APPLICATION.
6. Updates & Modifications
We reserve the right to modify these Terms & Conditions at any time. Updates will be posted on this page with an updated modification date. Continued use of SDM following any changes constitutes your acceptance of the updated terms.

Android Permissions Breakdown
SDM strictly adheres to Android's principle of least privilege. Every permission requested is essential to core download acceleration, battery management, or storage operations.
| Permission | Category | Why It Is Needed |
|---|---|---|
| FOREGROUND_SERVICE & DATA_SYNC |
Core Background | Keeps high-speed byte segments and torrent swarms active when you switch apps or lock your screen, preventing the OS from killing the transfer. |
| POST_NOTIFICATIONS | User Interface | Displays real-time download speeds, progress percentages, ETA, and quick Pause/Resume controls in the notification drawer. |
| SCHEDULE_EXACT_ALARM | Scheduling | Allows the scheduler to start or stop scheduled downloads at exact user-specified times (such as off-peak midnight Wi-Fi windows). |
| RECEIVE_BOOT_COMPLETED | Scheduling | Restores user-scheduled download alarms after your device is restarted so tasks fire accurately. |
| ACCESS_NETWORK_STATE & INTERNET |
Network | Transfers file data and detects whether the device is connected to unmetered Wi-Fi or cellular data to prevent overage charges. |
| WAKE_LOCK | Power | Prevents the device CPU from entering deep sleep while active file segments are downloading. |
| Storage Access Framework (SAF) | File System | Enables you to pick any folder on internal storage or external SD cards where completed files will be saved safely. |
💡 User Control Over Permissions
You can grant or revoke optional permissions at any time through your Android device settings (Settings > Apps > SDM > Permissions). Note that disabling background foreground services or network access may prevent downloads from completing in the background.
