Summary

While a session runs, Terevu reads your facial expression, eyes, head position and hands from your camera, only to notice when you drift from the expressions you've saved.

Terevu is designed to do all of this on your device. Camera images are processed for a moment to take measurements, then discarded. Terevu does not save or upload photos or video, does not access audio, and does not give Second Pass access to these measurements.

What's saved is numbers describing each expression you choose to save, not an image.

You can switch off or delete any saved expression at any time, or erase everything Terevu saved on this device in one step with Delete data from this device. Terevu is designed to keep its saved data out of iCloud, Time Machine and Android backups, so those services do not hold another copy. If you don't open Terevu for 12 months, it erases everything it saved the next time it opens.

What Terevu reads

When you save an expression or run a live session, Terevu uses your camera to derive numeric measurements, frame by frame, on your device:

  • Facial expression: the relative position and movement of points on your face, such as how far your brow is raised or how open your eyes are
  • Head position: tilt, turn, and whether your chin is raised or dropped
  • Face size in the frame: to notice when you lean in close or sit far back
  • Mouth shape held for a second or more, such as a grimace or pressed lips. Terevu is designed to disregard mouth movement from speech.
  • Where your eyes are looking: to notice an eye roll or a look held down at your phone
  • Your hands: only whether a hand is near your face

These measurements are derived from face geometry and may be treated as a biometric identifier or biometric information under laws such as the Illinois Biometric Information Privacy Act, the Texas Capture or Use of Biometric Identifier Act, the Colorado Privacy Act and Washington's biometric and consumer health data laws. Terevu is not designed or used to identify anyone, to recognize who a person is, or to infer emotions or mental states. Second Pass does not use these measurements to train AI models and does not provide them to anyone else.

Terevu does not save:

  • Photographs or video of you
  • Audio of any kind (Terevu does not access the microphone) (Terevu does not access the microphone)
  • Your name or identity, or anything that identifies you from the measurements
  • Biometric data from anyone other than the person using that device

Point the camera at yourself only. Terevu follows one face at a time. If someone else is more prominent in view, Terevu may read their face in the moment. Readings that are not part of an expression you choose to save are discarded.

What's saved

For each expression you choose to save, Terevu keeps a small set of numbers on your device: averaged expression scores, a head-orientation value, a face-size value, and averaged mouth-shape and gaze values. Your chosen cue sensitivity and any fine-tuning are saved too. If you choose Use this spot, Terevu also keeps the head angle and face size of that spot, and erases them together with the expressions they belong to. Hand measurements are used in the moment and not saved. Terevu does not save a record of your sessions or how you performed in them.

Starting with your calls

On a computer, you can choose to have Terevu start when a call begins. This is off until you turn it on. To know a call is happening, Terevu checks only whether your camera and microphone are in use, and by which app. Terevu does not request access to your microphone and does not access audio. That check is used in the moment and is not stored.

A session can keep running while Terevu's window is hidden behind your call. When it does, a menu-bar or system-tray indicator and a small floating cue show that it's on.

On an iPhone or iPad set beside your computer, the session runs on that iPhone or iPad alone, with its own camera, and the cue is a soft glow at the edge of its screen. It doesn't connect to your computer or your call.

How it's processed

Terevu is designed to take measurements only while you're saving an expression or while a live session is running, with your device's camera indicator on. Processing uses machine learning models that run on your device. Your device does the analysis itself, and Terevu is not designed to transmit measurements of your face, head or hands.

Why Terevu processes it

The sole purpose is the feature you chose Terevu for: comparing how you look right now to the expressions you've saved, so Terevu can give you a quiet cue when you drift. Second Pass does not use this data, and Terevu is not designed to use it, for facial recognition, identification, emotion recognition, advertising, analytics, AI training, or any other purpose.

Your consent

Terevu asks for your written consent in the app before the camera turns on for the first time. Checking the consent box is your electronic signature. Your agreement to the Terms of Service is a separate checkbox. Terevu records on your device that you consented, the date and time, and which version of the wording you agreed to. When what Terevu reads changes in a meaningful way, we ask again, and show what's new, before the camera turns on. Automatic start with your calls stays off until you've agreed to the current version.

You can withdraw your consent at any time with Delete data from this device, which also erases everything Terevu saved on that device. You do not have to agree to anything in order to delete.

If your employer provides Terevu, you'll see an employer version of this consent explaining what your organization can and can't see. Your organization may make Terevu part of a training or development program. That program, and any requirement to take part, is set by your organization under its own policies; Second Pass does not set, monitor or enforce it. You give your consent to Second Pass on your device, and you may withdraw it at any time with Delete data from this device, which also erases what Terevu saved there. Your organization sees only whether you have consented or withdrawn consent, not the reason. Any effect that withdrawing has on your organization's program is between you and your organization.

Where it's stored

Saved expressions are stored on your device, in storage designed to be accessible only to Terevu. Terevu is not designed to upload them to Second Pass or to any third party, and Second Pass operates no server that receives this data. Each device keeps its own saved expressions, and Terevu does not sync them between devices.

Terevu also marks its storage so that device backups, such as iCloud Backup, Time Machine and Android backup, leave it out. Deleting data in Terevu is therefore designed to leave no copy in those backups.

Retention and destruction schedule

  • When you ask: Remove erases a saved expression immediately. Delete data from this device erases everything Terevu keeps on that device, including the underlying storage files.
  • When you stop using an expression: each saved expression keeps its own clock. If it hasn't been used in a session for 12 months, Terevu erases it the next time it opens, after showing a notice in Your expressions a month before. Faces change over a year, so this also keeps your cue accurate. Using an expression in a session restarts its clock.
  • When you stop using Terevu: if Terevu isn't opened on a device for 12 months, everything it saved there is erased the next time it starts, and Terevu tells you it has done so. This is sooner than the one year required in Texas, the 24 months required in Colorado and the three years required in Illinois.
  • During a session: camera images and measurements that aren't part of a saved expression are discarded as soon as they're used, and are not stored.
  • Uninstalling: on an iPhone or iPad, deleting the app erases everything it saved. On a computer, use Delete data from this device first, because moving the app to the Trash or uninstalling may leave its saved data behind.
  • We review this schedule, and the app's deletion features, at least once a year.

Security and incident response

Saved expressions stay in Terevu's private storage on your device, protected by your device's own security. On a Mac or Windows PC, Terevu also encrypts them, with a key designed to be usable only by Terevu on that computer. We protect biometric data with a reasonable standard of care for our industry, and at least as carefully as we protect any other confidential or sensitive information. Because Terevu is not designed to send them to our systems, a breach of our systems would not be expected to expose them. If we learn of a flaw in Terevu that could expose saved expressions on a device, we will work to address it, and where applicable by law, tell affected people through the app and this site and notify authorities.

Sharing and disclosure

We do not sell, lease, trade or disclose biometric data, or otherwise profit from it as data. Purchases pay for Terevu's features, not for your data. Because Terevu is not designed to send it to Second Pass, we do not have access to it and would not be able to provide it if asked.

Your rights and choices

You can manage this data directly in the app, at any time:

  • Review what's saved in your expression library.
  • Switch off any saved expression without deleting it.
  • Delete any saved expression with Remove, or everything at once with Delete data from this device.
  • Withdraw consent with Delete data from this device, which also turns off saving expressions, live cues and automatic start. You can consent again later and start fresh.

Because Terevu is designed to store this data on your device, you manage it in the app rather than through a request to us. If you'd like help, write to hello@terevu.com.

How to delete your data

  • Everything at once: in Terevu, open Your expressions, scroll to Your data, and choose Delete data from this device. This erases every saved expression, your consent, your color and settings, and any Teams sign-in on that device, and turns off starting with calls and opening at login. It also withdraws your consent.
  • One device at a time: Terevu keeps your data separately on each device, so this erases it from the device you are using. Your other devices are not affected; repeat the step on each one you want cleared.
  • One expression: choose Remove beside it in Your expressions.
  • On a Mac or PC, use Delete data from this device before removing the app.
  • On an iPhone or iPad, deleting the app also erases everything it saved.

Your purchases are unaffected: they belong to your Apple ID, your Microsoft account or your Google account, and Restore purchases brings them back if you return.

If your employer provides Terevu

This policy governs your biometric data in full. It is processed on your device, and the admin console is not designed to show it to your employer. The admin console shows only the name and work email you were invited with, your seat type, and your seat status (invited, active or consent withdrawn) with its date. It is not designed to show your saved expressions, calibration content or camera activity, or how often you use Terevu.

Age requirement

Terevu is intended for people 18 years of age or older. Terevu is not offered to anyone under 18. If you believe a minor has used Terevu, deleting the app from their device removes everything; contact us if you need help.

Changes to this policy

If we make a material change to what Terevu reads or how it's used, we'll update this page and ask for your consent again in the app before continuing.
