Frequently Asked Questions
How much does it cost right now?
Nothing. Interlaza is free for everyone during our testing phase, until 30 November 2026 — every plan, no credit card required. We'll announce pricing before the phase ends, with plenty of notice.
Can I cancel anytime?
Yes. Cancel from your account settings at any time before the billing period ends. You keep access until the end of the paid period.
Who owns the clinical data?
You do. All session data is stored locally on your device. Cloud sync is optional. We never sell or share clinical data — it belongs entirely to you and your students.
Can I manage more than one student?
The Family plan supports a single learner. Professional includes up to 5 students at a flat monthly price. Researcher covers up to 25 students. Institution offers up to 100 students with custom pricing.
Is it suitable for school or clinic use?
Yes. The Professional plan is designed for clinical and school settings. The Institution plan adds organizational management features for clinics, schools, and multi-professional teams.
What payment methods do you accept?
Major credit and debit cards via Lemon Squeezy, our secure payment provider. VAT and invoices are handled automatically. Contact us with any billing inquiries.
What device do I need?
Interlaza runs in the browser — nothing to install, though you can add it to the home screen and use it like an app, offline included. The child-facing screen scales to whatever size it is given and never shrinks a touch target below 80 px, so a phone works. A 10-inch tablet is the best size: that is where the images render at full scale. A 7–8 inch tablet is comfortable too. Instructors can plan sessions and record off-tablet trials from a phone or computer.
Does it work offline?
Yes. The app (interlaza.app) works fully offline — sessions run without an internet connection, and everything is stored on the device. Cloud backup is off until you turn it on; if you have turned it on, queued data syncs when the connection comes back.
What languages does the app support?
The app is fully bilingual: English and Spanish. The interface, exercises, and all student-facing content support both languages. Additional languages are planned for future releases.
