Privacy Policy
Last updated: July 17, 2026
Wispr Back is a macOS app that turns selected text, screenshots, and coding-agent output into spoken summaries. It is operated by Bishal Banerjee. This page explains what the app and website handle in plain language. The short version: your content is sent away only when it needs to be processed, we do not store that content on our servers, and your history stays on your Mac. We do not sell your data.
What we collect
- Account information. Clerk handles sign-in by email or Google. Clerk gives us the basic account details you choose to share, such as your email address, name, and profile image. We use them to identify your account and team membership.
- Selected text and screenshots. When you ask Wispr Back to process something, the selected text or screenshot is sent over an encrypted connection to our backend proxy and then to the provider needed for that request. We do not store the text or screenshot on our servers. Your screenshots, summaries, history, and audio are stored locally on your Mac and can be cleared in the app.
- Usage metadata. We record per-request metering (timestamps, model used, token counts, and processing cost) so the service can track usage and cost. This metadata does not include your selected text, screenshots, summaries, audio, or future call transcripts.
- Payments. Billing is not live today. We plan to use Razorpay for payments in India. When billing launches, Razorpay will handle payment details; Wispr Back will not store your card information.
Where processing happens
Clerk handles authentication. Our backend proxy relays summary requests through OpenRouter, which can route them to Google Gemini models, xAI Grok, or OpenAI. Cartesia handles voice synthesis when you use a Cartesia voice. Razorpay will handle payments in India once billing is live. Each service receives only what it needs for the request.
Future Calls feature
Calls is not live yet. During a future call, Wispr Back will send microphone audio through the same backend proxy for transcription. The running transcript will be kept in memory only and discarded when the call ends. One text recap will be saved locally on your Mac; the microphone audio and transcript will not be stored on our servers.
Retention
We keep account records and usage metadata while your account is active. Selected text, screenshots, summaries, audio, and call transcripts are not kept on our servers. Local history, audio, screenshots, summaries, and future call recaps stay on your Mac until you remove them.
Closing your account
Account closure is a soft-delete. Your old server-side account and usage records become orphaned and unreachable from the app, rather than being physically erased immediately. You can later register with the same email address and receive a fresh account that is not connected to the old one. Closing an account does not remove files already stored locally on your Mac; clear those in the app if you want to remove them too.
To ask about your account or close it, email support@composer1.com.
Security
All transport is encrypted (TLS). API credentials for model providers are held server-side and are never distributed inside the app.
Children
Wispr Back is not directed at children under 13 and we do not knowingly collect their data.
Changes
We will update this page and the date above when the product or its data handling changes.
