Privacy Policy
Effective 24 April 2026 · Last updated 24 June 2026
Interpreter Pro is a Chrome extension that writes a live transcript and translation beside an interpreter's calls. This is the plain-English version — written the way a careful engineer would explain it to a colleague, not a contract.
The short version
- We don't store your audio. When you record, it streams straight from your browser to one transcription provider (Soniox, under a signed BAA) and is gone when your session ends. On the normal path it never even touches our servers.
- Your transcript stays on your device, in your browser. We never receive it.
- No accounts. We don't collect your name, email, or phone number. (On paid plans your email goes to our payment provider for billing — never to us.)
- Signed BAA on every tier, so it's suitable for calls involving health information (PHI).
- You're the only voice on the call. Nothing records until you press Record, and we never touch your microphone.
If you don't have our data, we can't lose it. That's the whole design. The rest of this page is the detail behind those promises.
What we collect, and where it goes
Audio — never stored
When you press Record, the extension captures the audio of the browser tab you're interpreting on — the call on LanguageLine, Propio, Voiance, Zoom, Teams, or any browser-based platform. Never your microphone. Browser echo-cancellation means the tab carries only the other people on the call, not your own voice.
On the normal path, that audio streams — encrypted, in real time — straight from your browser to Soniox, which transcribes and translates it in a single session under a signed Business Associate Agreement (BAA). Our server's only job is to hand out a short-lived access key; your audio never passes through our servers at all.
If you turn on chunked (non-streaming) mode, run an older version, or Soniox is temporarily down, the audio is instead relayed through our Cloudflare Worker — held in memory only long enough to forward it, never written to disk — to Soniox or a BAA-covered standby provider. Recording stops the instant you press Stop or close the panel. Nothing records in the background.
Transcripts — on your device only
The transcribed and translated text is returned to your browser and stored locally, on your computer. It stays there until you click Clear transcript or uninstall the extension. We never receive your transcripts.
Edited lines and re-translations — text only
When you correct a line and it re-translates (or you click its re-translate icon), just that one line's text — never audio — is routed through our Worker to a translation model: Azure OpenAI on Free, or Google Gemini (via AssemblyAI) on paid plans. Both routes are BAA-covered. The result comes back to your device.
Word definitions — one word at a time
When you double-click a word to define it, that single word plus your language codes goes to Cerebras. The surrounding sentence, the rest of the transcript, and the audio are never included. Terms you save are stored in your browser, not on our servers.
A usage counter — minutes, not identity
On install, the extension makes up a random ID and reports how many minutes you've recorded this month, so we can enforce the free tier's 120-minutes-per-month allowance. The counter resets monthly. We don't tie that ID to your name, email, or anything identifying, and we never log what was said — only elapsed recording time.
Settings — on your device
Your language pair and interface preferences stay in your browser. We don't see them.
License key — paid plans
When you upgrade, LemonSqueezy emails you a license key; you paste it into the extension, which checks it with LemonSqueezy. For Pro that confirms an active subscription. For pay-as-you-go we keep a prepaid balance of recording minutes tied to your LemonSqueezy customer id (not to anything identifying), counted down as you record. Nothing else is kept.
Network metadata — Cloudflare
Like any web service, our infrastructure provider (Cloudflare) logs standard request data — IP address, timestamp, response status — for routing and abuse prevention. On paid plans we may store a salted, one-way hash of your IP for up to 30 days to detect license sharing, never the raw address. This is governed by Cloudflare's privacy policy and this one.
Who processes your data
A handful of services help run Interpreter Pro. We keep the list short and tell you exactly what each one touches — most never see your audio at all.
- Transcription & translation On the normal path your audio streams only to Soniox (signed BAA) and nowhere else. If Soniox is unavailable, or you use chunked mode, a standby steps in: Microsoft Azure OpenAI then OpenAI on Free, or AssemblyAI (with Google Gemini for translation, via AssemblyAI's gateway) on paid plans. Every one is BAA-covered.
- Word definitions When you double-click a word, that single word — no sentence, no transcript, no audio — goes to Cerebras. No BAA, because nothing identifiable is ever sent.
- Hosting & routing Cloudflare runs our server layer and handles request metadata. It never stores your audio or transcripts.
- Payments LemonSqueezy is our merchant of record on paid plans. Your name, email, and card details go to them, never to us — the extension only ever receives a license key.
Website analytics
This website (the page you're reading, and our landing page) uses privacy-friendly, cookieless analytics — Plausible and Cloudflare Web Analytics — to count visits. No cookies, no cross-site tracking, no personal data, nothing sold or shared with advertisers. The extension itself sends no analytics, telemetry, or crash reports beyond the minute counter described above.
What we never collect
- Your microphone, ever — we don't request or capture mic input.
- Names, phone numbers, or addresses (on paid plans, LemonSqueezy collects your billing details; we never see them).
- Browsing history, or anything on tabs other than the call audio you choose to share when you press Record.
- Data from other tabs or other extensions.
- Telemetry or crash reports from the extension. (Website visits are counted with the cookieless analytics described above.)
Your rights
- Delete your local data: Click Clear transcript in the settings panel, or uninstall the extension. Either one wipes everything we store on your device.
- Cancel a paid plan: Use the LemonSqueezy customer portal (link in your confirmation email) to cancel or pause. You keep access through the end of the current billing cycle.
- Reset your free-tier counter: Uninstall and reinstall — Chrome deletes the extension's stored data (including the random ID), and a fresh one is made on the next request. We can't technically prevent this, but please use it sparingly; it's how we keep the free tier sustainable.
- Request deletion from a provider: Contact Soniox, Microsoft, OpenAI, AssemblyAI, Google, Cerebras, or Cloudflare directly via their published procedures. We have no special access to their stored data on your behalf.
- Training opt-out: Soniox, Microsoft Azure OpenAI, AssemblyAI, Google (via AssemblyAI's gateway), and OpenAI do not use customer API data for model training under their default enterprise terms as of the date above.
Compliance
- GDPR: We process minimal personal data (a random ID and a monthly counter). We are not established in the EU and have not negotiated bespoke Data Processing Agreements with our providers beyond their default terms. EU users should consider this before use.
- Children: The extension is not intended for users under 13. We do not knowingly collect data from children.
- Certifications (HITRUST, SOC 2): We are not separately certified. Microsoft Azure and AssemblyAI are each SOC 2 Type 2 certified.
- Payments (PCI DSS): Not in scope — we never process payment data ourselves; LemonSqueezy handles it.
- Legal proceedings: Transcripts are not validated for legal admissibility. Machine transcription can contain errors and should be verified by a human before any legal use.
Changes to this policy
We may update this policy when our data practices change. The Last updated date at the top reflects the latest revision, and material changes are noted in the extension's Chrome Web Store release notes.
