Why Clearbase

The internet has a business model problem

Most "free" software is free because you pay with your attention, habits, and identity. We built Clearbase on a different model: you pay a fair price, we build tools that serve you.

Honest about what we send and where
Your audio never leaves your device, and your transcripts stay on your device too, unless you choose to save a conversation to your account for later review. Questions are sent over encrypted HTTPS, and on our own server we keep only a one-way fingerprint of each question, never the text of what you asked. We don't sell your data, and you can delete your account and everything tied to it at any time.
No ad networks, ever
A privacy company that uses Google AdSense is not a privacy company. We will never embed ad networks that track your behavior across the internet.
Transparent by default
We publish exactly what API calls are made and what data is sent. No vague policy language. If it touches a server, we tell you which one and why. You will find the specifics in each product's dedicated section.
One team, no investors
A small but dedicated team of engineers with no VC pressure to monetize users. No board pushing for growth at your expense. Your interests and our interests are exactly the same.
Delete anytime, for real
Request account deletion and every record is purged within 30 days. No "we'll archive it for 90 days" asterisks.
No surveillance capitalism
We earn revenue from subscriptions, and the free tier may include privacy-respecting contextual ads to help cover server costs. No behavioral tracking. No data sales. No ad networks that profile you. What you pay for is what you get.
How it works

Designed to protect you at every step

Here is exactly what happens when you use Whispr.

01
You install the desktop app
Whispr runs natively on Windows. It uses OS-level rendering so it's invisible to screen-capture software. Your interviewer sees only your screen, not Whispr.
02
Audio captured locally stays on your device
Whispr listens to your meeting audio directly on your machine. The audio itself is never uploaded or transmitted anywhere. It is processed and discarded locally.
03
Question text is sent for AI processing
When a question is detected or typed, the question text is sent to a third-party AI provider (Cerebras or Google Gemini) to generate your answer. On our own server we keep only a one-way fingerprint of each question plus basic usage counts for abuse detection, never the question text itself. Short transcript snippets are sent to the AI provider for question detection (up to 5,000 characters) and for generating answers (up to 3,000 characters). No audio. No full transcripts. The answer appears in your overlay within seconds.
04
Session ends, audio and transcripts discarded
When your session closes, audio and transcripts are permanently discarded from your device. The only information we store is your account, basic usage records (for abuse monitoring and server traffic costs), and any conversations you choose to save, connected directly to your account for your eyes only. All of this is controlled by you. Delete your account and everything tied to it is purged within 30 days, no middleman, no exceptions.

Which servers handle your data: Our own server for account authentication and session metadata. Cerebras (US-based) for AI responses, with Google's paid Gemini API as a fallback. Both process requests without training on your data.

Whispr · Active session
💬 "Walk me through how you'd design a rate limiter."
A rate limiter can be implemented with a token bucket or sliding window approach. I'd store request counts in Redis with a TTL equal to your window size, increment on each request, and reject once over the limit. For distributed systems, use a Lua script to make the increment-and-check atomic...

Privacy promise

Exactly what we do with your data

No vague policy language. Concrete commitments, in plain English.

Audio & video

Meeting audio never leaves your device. Captured locally, processed locally, discarded when the session ends.

AI processing

Your audio stays on your device. Short text snippets are sent to AI APIs for question detection and answering. Never audio. Never full transcripts. On our own server we keep only a one-way fingerprint of each question plus usage counts to detect abuse, never the question text. This is disclosed, not hidden.

Cerebras (AI responses): A US-based provider. Cerebras states that inference inputs and outputs are not stored, logged, or reused, and are processed only to generate your response. Cerebras policies

Gemini (fallback, paid API): Requests routed through Google's paid API. Google does not use your prompts to improve its products, and prompts are not used to train AI models. Gemini data policy

Usage monitoring

We run an internal admin dashboard that tracks session counts, LLM call frequency, and token usage per account. We are transparent that this exists. Its purpose is to detect abuse such as API abuse, rate limit violations, and spam signups, so that the free tier stays genuinely free for real users. This data is never sold and is not shared with third parties. You can request a full export or deletion of your usage data at any time.

Analytics

We use Cloudflare Web Analytics. Privacy-respecting, no cookies, no fingerprinting. No Google Analytics, no Facebook Pixel.

Advertising

When the free tier includes ads, we plan to use a privacy-respecting network like EthicalAds: contextual targeting only, no tracking cookies, no behavioral profiling. We will never use Google AdSense. (Not live yet.)

Data sharing

We don't sell your data. We don't share it with data brokers.

Account deletion

Request deletion and every record we hold about you is purged within 30 days. No exceptions, no backup archives retained.

Open by design

Don't trust us, verify us

Any privacy company can write a policy. We show you the actual code. Here's exactly what Whispr sends to AI providers, and what it leaves on your machine.

llm_service.py What we send to AI
# From llm_service.py: what we send to the AI provider # Audio? Never touches this function. # Full transcript? Truncated to last 3,000 chars max. # Your identity? Not included. async def generate_answer(question, doc_context, transcript, ...): parts = [] # Prepared Q&A pairs if you loaded a document if prepared_qas: parts.append(f"## PREPARED Q&A\n{prepared_qas}") # Uploaded document or prior conversation context if doc_context: parts.append(f"## DOCUMENTS\n{doc_context}") # Last 3,000 chars of transcript only, not the full session if transcript: parts.append(f"## TRANSCRIPT\n{transcript[-3000:]}") # Your question, typed or auto-detected parts.append(f"## QUESTION\n{question}") # That is everything sent. Nothing else leaves your machine. return await _call_llm(provider, model, system, "\n\n".join(parts))
These are real excerpts from Whispr's codebase. We show this because the strongest privacy claim is one you can verify yourself. If you have questions about any specific data flow, reach out directly and we will walk you through it.
