Privacy Policy

Echo · Last updated 7 October 2026

Echo records your voice, transcribes it, and summarises it. That means we handle recordings of you speaking, which is personal and sometimes sensitive. This page explains exactly what we collect, who else sees it, and how to get rid of it.

Who we are

Echo is made by CNTXT. If you have a question about anything here, email support@cntxt.tech.

What we collect

What we do not collect

We do not upload your contacts: if you pick someone from your contacts to call, only the number you chose is sent. We do not collect your location, your photo library beyond images you deliberately attach, or your browsing activity. Echo shows no ads. We do not sell your data. The content of your notes, recordings and transcripts is never shared for advertising.

How your audio is processed

This is the part worth reading carefully.

When you finish a recording, the audio is uploaded to our storage and then sent to the Munsit speech service (operated by Faseeh), a speech-recognition provider specialising in Arabic, which produces the transcript and identifies the different speakers in it (so the transcript can show who said what). Your audio therefore leaves our systems and is processed on Munsit's infrastructure. Munsit acts as our processor and is not permitted to use your recordings for its own purposes.

Transcription is machine-generated. No human at CNTXT listens to your recordings as part of normal operation.

Recording phone calls

iPhone does not let apps record phone calls, so Echo uses Twilio, a telephone provider in the United States. When you record a call, Twilio calls your phone, connects the other person (or joins the call you merge in), and records the call. When you call someone through Echo, they hear that the call is being recorded before they are connected. Twilio also sends the SMS code that confirms your number and, if you set it up, places the short call that verifies your number as your caller ID.

Twilio therefore receives your phone number, the other person's number, and the call's audio. As soon as the recording has been copied to our storage, we delete it from Twilio. From there it is transcribed and summarised like any other recording. Twilio acts as our processor and is not permitted to use your calls for its own purposes.

You are responsible for making sure recording a call is allowed where you and the other person are, and, when you merge Echo into a call, for telling the other person it is being recorded.

AI services that process your notes

Echo sends the text of your notes (the transcript, and the summary where there is one) to OpenAI, an AI provider in the United States:

Your audio is never sent to OpenAI. OpenAI processes this text on our behalf through its API, and under its API terms it does not use it to train its models.

Where your data is stored

Accounts, notes, transcripts, recordings and attachments are stored with Supabase, in a database and object storage hosted in Mumbai, India (ap-south-1). If you are in the Gulf, the EU or the UK, this means your data is transferred outside your region and stored there.

Access is restricted at the database level: every table enforces row-level security so one account cannot read another's rows, and recordings sit in private buckets reachable only through short-lived signed links issued to you.

Analytics and ad measurement

Payments

Subscriptions are purchased through the Apple App Store or Google Play and managed for us by RevenueCat, which tells us whether your subscription is active. Card and payment details are handled entirely by Apple or Google. We never see, receive or store them.

Sign in with Apple and Hide My Email

If you use Sign in with Apple and choose to hide your address, we only ever receive Apple's relay address. That is fine — everything in Echo works with it.

How long we keep things

Your notes, recordings, transcripts and Ask Echo conversations are kept until you delete them or delete your account. Calendar meetings are kept only until they have passed, and are removed when you disconnect the calendar. Deleting a note removes it and its audio. Usage records for a billing period are kept for as long as we need them to operate the free tier and to answer billing questions.

Deleting your account

Settings → Delete account removes your account permanently. It deletes your recordings and attached images from storage, and your notes, transcripts, summaries, Ask Echo conversations, comments, to-dos, folders, connected calendars, your phone number, your call history and usage history from the database. It cannot be undone, and we cannot recover anything afterwards.

Cancelling a subscription is separate and is done through the App Store or Google Play — deleting your account does not cancel a subscription for you.

Your rights

You can access, correct, export and delete your data from inside the app. Depending on where you live you may also have the right to object to or restrict processing, or to complain to a data protection authority. Write to support@cntxt.tech and we will help.

Children

Echo is not intended for children under 13, and we do not knowingly collect data from them. If you believe a child has created an account, contact us and we will delete it.

Security

Traffic is encrypted in transit. Recordings are stored in private buckets and are never publicly listable. No system is perfectly secure, and we will not claim otherwise — but we do not keep your data anywhere it can be read without authentication.

Changes to this policy

If we change this policy in a way that materially affects you, we will update the date at the top and tell you in the app before the change takes effect.
