Privacy policy

Engine tools, Salt Lake Consultants LLP. Last updated: 15 November 2026.

Who this applies to

The Engine tools are private, in-house applications used only by their owner, Vivek Mohan Mehta, for Salt Lake Consultants LLP. They are not available to the public. The only Google account that signs in to them is the owner's own account.

What data the tools access

• Engine Mail Reader uses Google's Gmail permissions to read messages in the owner's Gmail account from a short list of senders the owner has chosen, and to add a copy of an internal notification message to the same mailbox. It cannot send or delete mail.
• Engine Backup uses Google's Drive permission for files the app itself creates. It uploads backup files to a folder in the owner's Google Drive and cannot see any other file in Drive.

How the data is used and stored

Data is used only to provide these internal features to the owner: to read the calls and alerts the owner has chosen to receive, and to keep backups of the owner's own data. It is processed on servers controlled by the owner. Sign-in tokens are stored on those servers, are not shared, and are not included in backups, documentation or logs.

Sharing and disclosure

The data is not sold, shared with or transferred to any third party, and is not used for advertising or to train artificial-intelligence models, except where required by law.

Google API Services User Data Policy

The use and transfer to any other app of information received from Google APIs will adhere to the Google API Services User Data Policy, including the Limited Use requirements.

Retention and deletion

Mail data is kept only as long as the owner needs it for the internal features described above. Backup files are kept for a limited number of days and then deleted. The owner can revoke the tools' access at any time in the Google Account permissions page, and can delete all stored data and tokens from the servers.
