noTubex (Mentalism & Prediction App)
A Notes-style Android mentalism utility for song, image and custom-page reveals on a consenting spectator's phone. Includes a web receiver you host and configure.
What you can do
noTubex turns an everyday Notes-style interface into a performance companion for close-up mentalism. Developed by rajeshbiswas.me for TrickApps, it combines a discreet performer dashboard with a browser receiver so a participant can see a song, image search or custom reveal on their own phone. Build three kinds of routine: a live reveal controlled from your Android phone, a deleted-note prediction using a non-sensitive choice entered within the app, or an object and celebrity reveal through image search or a custom page. The performance is an entertainment illusion that depends on your preparation and presentation. The performer controls include a dark pocket screen, typed input, optional voice recognition, haptic status feedback and a reusable QR code with save and share controls. Your spectator needs only a suitable browser and, for the QR routine, a camera or QR scanner. This is a configurable software package. You provide a Firebase Realtime Database for the performance data and host the included single-file web receiver. It is intended for consensual magic routines using harmless song titles, objects and similar choices. Participant input may be retained and sent to your configured service, even when it is deleted from the visible note. Explain that input may be processed for the routine; never request passwords, payment information or private personal content. YouTube and Google links open external services. Search matches, availability, playback and browser autoplay depend on those services and the spectator's device. noTubex is independently developed and is not affiliated with or endorsed by YouTube, Google or Firebase.

- The receiver reads a demonstration channel without performer authentication. Its database address is visible to browsers; use a dedicated database, limit its access and remove unused routine data.
- The automatic video resolver may select a different match or fall back to YouTube search. Internet access, external services and autoplay are not guaranteed.
- The Notes interface is a performance disguise, not a private notes storage service.

- Refunds
- Refund Policy This policy applies to our paid apps, digital products and subscription charges. Any additional refund promise shown before purchase also applies. ## When we offer refunds We will refund verified duplicate charges. If you do not receive the purchased download, access or required activation after the stated delivery period, contact us so we can complete delivery. If we cannot deliver, we will refund the affected purchase. If a reproducible fault prevents an advertised feature from working on a supported device or setup, contact us with the details. We may offer troubleshooting, a fix or a replacement. If we cannot provide the advertised functionality within a reasonable time, we will offer an appropriate refund. You retain any right to an earlier or different remedy under applicable law. ## Change of mind and compatibility Please review the description, compatibility requirements and limitations before buying. A change of mind, a feature that was never advertised, or use on a clearly disclosed unsupported setup does not automatically qualify for a refund. This does not limit rights concerning faulty, misdescribed or undelivered products. ## Subscriptions You can cancel future renewals through the service where you subscribed. Uninstalling the app does not cancel a subscription. Cancellation normally takes effect at the end of the paid period and does not automatically refund past charges. Renewal charges remain eligible for review under this policy and applicable law. ## How to request a refund Contact the support address listed in the app, on the product page or on your receipt. Include your purchase email, app name, order or receipt number and a description of the issue. For technical problems, include your device and operating-system version. Do not send passwords, activation keys or full payment-card details. Contact us promptly. This policy does not shorten any statutory or payment-provider claim deadline. Processing and access Approved refunds are returned through the original payment provider to the original payment method, where available. Processing time depends on the provider and your bank. Purchases through an app store or another merchant of record may need to be refunded through that seller and are also subject to its rules. A full refund ends the license or paid access associated with the refunded purchase or subscription period. We will explain any access changes accompanying a partial refund. A refund does not itself remove local files or guarantee that an offline activation key stops working immediately. Your rights Nothing in this policy excludes mandatory consumer rights, including applicable remedies or withdrawal rights for digital content and services. Any legally required consent to immediate digital delivery must be handled separately at checkout. Where this policy conflicts with mandatory law or binding seller/payment-provider rules, those protections take precedence.

Questions about noTubex (Mentalism & Prediction App)
Does the spectator install an app?
No. The performer installs the Android app. The spectator opens your hosted receiver in a suitable web browser, directly or through your QR code.
What do I need to configure?
You supply a Firebase Realtime Database dedicated to the routine and host the included web receiver. Set both addresses in the performer dashboard and rehearse before a show.
Is an activation key required?
Yes. The updated release requires a signed key tied to your purchase email and the Device ID shown in the app. Install the locked APK, confirm its Device ID before purchase, then retrieve the key from your library and activate that device. A Lifetime key has no expiry.
Can I use personal information for a routine?
Use only harmless choices with informed participant permission. Inputs may be retained and transmitted to your configured service even after deletion from the displayed note. Never request passwords, payment information or other sensitive data.
Will every song play automatically?
No. Results depend on third-party search and content availability, and browser autoplay restrictions may require a tap. The app includes a search fallback.
When do I choose my performance URL?
After activation, choose the performer name in the app dashboard and configure the receiver and its matching database. The app generates /name and /name/live links on your configured receiver host. Names are not reserved or checked for exclusive ownership; managed shared-domain hosting is not included.
