FAQ
Common questions
What is bilateral stimulation in EMDR therapy?
Bilateral stimulation (BLS) is the alternating left–right stimulation — visual, auditory or tactile — used in EMDR to support the brain’s Adaptive Information Processing of distressing memories.
How does online EMDR with BilateralSync work?
You create a session, share the secure link with your client, and control the visual and auditory bilateral stimulation in real time. The client sees only the calming target — nothing else.
Does my client need an account or installation?
No. Your client opens the link in any modern browser on desktop, tablet or phone. No app, no account, no downloads.
Is BilateralSync GDPR‑ready?
Yes. Sessions use unguessable codes, no client PII is collected, and we use cookieless, anonymous analytics.
Can I use auditory bilateral stimulation?
Yes. Stereo left/right panned tones with adjustable frequency and volume play in perfect sync with the visual target.
Does it work with Zoom, Teams and Doxy.me?
Yes. The client view is a plain URL — it runs alongside any video platform. Most therapists share it through the in‑call chat.
Is BilateralSync a medical device?
No. BilateralSync is a clinical tool for trained EMDR therapists. It is not a medical device and does not replace clinical training or a therapeutic relationship.
Which devices and browsers are supported?
Chrome, Safari, Firefox and Edge on macOS, Windows, iPadOS, iOS and Android.
