Frequently asked questions

Can’t find your answer? Ask on your teardown call, or email demari@tecplus.io.

Get a free teardown
Is the teardown really free?

Yes. No card, no contract. If we’re not the right fit for your app, we’ll tell you.

Do I need to be technical?

No. Everything comes in plain English, and the walkthrough call is there for questions. If someone technical helped build the app, bring them along.

Someone else built my app. Is that OK?

Yes. Most apps we see were built with AI, by a freelancer, or by an agency that has moved on.

What’s the difference between the teardown and the Full Audit?

The teardown checks your single riskiest area in 24 hours, free. The Full Audit covers all six areas in 7 days, with a full report, a fix-first plan and a walkthrough call.

Do you fix things, or just tell me what’s wrong?

The teardown and Full Audit show you what is wrong and what to fix first. If you want help after that, you can ask Demari to make the fixes one at a time.

What do you need from me?

A 30-minute handoff call, a link to the app and enough access to review the part that worries you. Start with view-only access when possible.

Is my code and customer data kept private?

Yes. Access is used only for the review, shared with no one and removed when the work is done. An NDA is available on request.

How do I follow along?

Active clients get a private workspace for the report, fix list and progress.

What happens after the Full Audit?

You keep the report and the plan. Fix it with your team, or ask Demari for ongoing monthly help.

Do you offer refunds?

If the Full Audit is not a fit after the first week, ask for a 75% refund.
