Privacy notice

Before using the online flasher, confirm how this page handles firmware and serial data. The following terms apply only to the current browser session.

• Firmware is not stored or uploaded. The file you select stays in this browser’s memory for the current flash only, and is released when you leave the page or close the tab. This page does not write the file to site storage and does not send it to Ai-Thinker servers.
• Firmware runtime behavior is not analyzed. This page does not decompile the firmware or reconstruct its features or code behavior. It writes the data to the device using that module’s flash protocol only.
• Serial traffic stays on this machine. Data moves only between this browser and the connected device. It is not forwarded to Ai-Thinker servers or any third party.
• Integrity checks stay local. MD5, CRC, and SHA256 are computed only to verify that the file is intact. The results do not leave this machine.

Choosing “I understand” only confirms that you have read this notice. The choice is not saved, and this page will ask again the next time you open it.
