Pioneering the future of cognitive wellness.

We collect the minimum required to run GLISSA: your account email, your in-app preferences, and anonymised usage events that tell us whether a protocol was completed. We do not record audio, we do not access your microphone, and we do not build advertising profiles.

Your data is never sold or brokered. You can export or permanently delete everything from within the app, and deletion is honoured within thirty days across every system we operate.

GLISSA is licensed to you for personal, non-commercial use. You keep ownership of anything you create in the app; we keep ownership of the app, its audio, and its protocols.

GLISSA supports rest and relaxation. It is not a medical device and it does not diagnose, treat, cure or prevent any condition. GLISSA is intended only for adults aged 18 and above and should not be used during pregnancy. Do not use audio protocols while driving or operating machinery.

GLISSA subscriptions are purchased and managed through the applicable app-store billing system. Depending on platform and region, supported checkout methods may include Google Play billing, Apple billing, cards, UPI and Apple Pay. Cancellation is managed through the store account used for purchase; access normally continues until the end of the paid period, and cancelling does not delete your data.

Refunds are generally handled under the policy of the store or payment platform through which the purchase was made. If you believe there is a genuine billing issue, contact us and we will help investigate.

Data is encrypted in transit with TLS and at rest in our database. Access is restricted to the people who need it, authentication is handled by a dedicated provider, and payments never touch our servers.

We operate in line with India's Digital Personal Data Protection Act. You have the right to access, correct, and erase your personal data, and to withdraw consent at any time.

For the binaural protocols, yes. A binaural beat is produced inside your brain from two slightly different tones, one in each ear. Speakers let the tones mix in the air before they reach you, and the effect is lost. Any ordinary pair of headphones or earbuds works — there is no need for expensive ones.

GLISSA is designed to help you fall asleep by guiding your mind and body toward a calmer, sleep-ready state. Its neuroscience-informed audio experience is designed to settle mental activity and support the natural transition from wakefulness toward sleep. Individual experiences can vary, and GLISSA is a wellness tool—not a medical device or treatment for insomnia or any other medical condition.

Our audio begins with a beat frequency of ten cycles per second — the alpha rhythm of a relaxed, awake brain — and lowers it continuously through theta and into delta, around one cycle per second, which dominates deep sleep. The descent is generated mathematically rather than assembled from loops, so the frequency never steps or jumps.

GLISSA is intended only for adults aged 18 and above and should not be used by children or adolescents under 18 or during pregnancy. If you have epilepsy or a seizure disorder, a neurological or mental health condition, or another medical concern that could make rhythmic audio unsuitable, consult a qualified healthcare professional before use. GLISSA supports relaxation and sleep routines and is not a substitute for clinical care.
