Privacy Policy

Effective date: 24 September 2026

Last updated: 10 November 2026

This Privacy Policy explains how NEXO ("NEXO", "we", "us" or "our") handles information when you use the NEXO: Scan, Chat & Print mobile application (the "App"). We have written it to be read, not skimmed past: the short version is that your documents stay on your phone.

1. The short version

• NEXO works offline. Scanning, text recognition, search, PDF tools, Smart Vaults and NEXO Chat all run on your device.
• We do not operate accounts, cloud storage or servers that receive your documents, scans, extracted text or chat history. We never see them.
• The free version shows ads provided by Google AdMob. Google may collect device information for advertising, as described in section 5. NEXO Pro removes ads.
• Purchases are handled entirely by Google Play. We never see your payment details.
• If you contact us (for example with "Report a problem"), we receive only what you choose to send in that email.

2. Who we are

The App is provided by NEXO, based in India. For the purposes of India's Digital Personal Data Protection Act, 2023 (the "DPDP Act") and, where it applies, the EU/UK General Data Protection Regulation ("GDPR"), NEXO is responsible for the limited personal data it processes as described in this policy.

Contact: [email protected]

3. Information that stays on your device

The following is created and stored only on your device, inside the App's private storage, which Android encrypts. It is not sent to us or to anyone else unless you choose to share it:

• Documents you scan, import, create or edit, including PDFs, images and their thumbnails.
• Text recognised from your documents, summaries, detected dates, amounts and categories.
• NEXO Chat conversations and the on-device search index built from your documents.
• Smart Vault organisation, including vaults you create yourself and the documents you add to them, favourites, tags, reminders, due dates and the dates and corrections shown in a vault's Timeline.
• Documents you delete, which move to a Trash Bin on your device. They stay there, with their details, until you restore them or delete them permanently, or empty the Trash Bin.
• Text you select, copy or extract from a PDF, and your list of recent PDFs. Text is saved to your phone only if you choose to save it.
• PDFs you open in NEXO from another app, which are kept in the App's private storage so that you can find, search and ask about them.
• Counters for the free version's daily and monthly limits (such as NEXO Chat questions and translated pages) and your Pro status as last confirmed by Google Play.
• Your display name, app language, theme and other settings.
• Technical error logs, which contain short technical notes and never your document content.

The App's private data is excluded from Android cloud backups, so it is not copied to your Google account backup. If you move to a new phone with Android's phone-to-phone transfer, which you start yourself and which goes directly between your two phones, your library, scans and settings can come with you; they are not sent to us. This also means that if you uninstall the App, clear its data or lose your device without transferring it, this data cannot be recovered by us. Please export or share copies of important documents to a location you trust. Files you have saved outside the App (for example to Downloads or a folder you selected) remain there until you delete them.

Backup and restore (your choice). In Settings you can back up your library to one file, locked with a password you choose, and save it wherever you decide (for example Google Drive, a memory card or your computer). NEXO creates the file on your phone and does not upload it. We never receive your password and cannot recover it, so a backup you cannot unlock cannot be opened by anyone. Restoring a backup replaces the library on that phone.

Temporary files created while processing, printing or sharing are deleted automatically, normally within a day.

4. Information we receive from you

We only receive personal data when you contact us directly, for example through "Report a problem", which opens your own email app with a pre-filled message. You review the email before sending it. We receive:

• Your email address and name as shown by your email provider.
• The subject, message and any attachments you choose to add. Please do not attach documents containing sensitive personal information unless it is needed to solve your problem.
• Device details (app version, device model and Android version), only if you tick "Include device details".

We use this information only to respond to you, investigate and fix the problem, and improve the App. We keep support emails for as long as needed to resolve your request and for up to 24 months afterwards, unless the law requires us to keep them longer. We do not sell this information or use it for advertising.

5. Services provided by third parties

Some features rely on services from other companies. These companies process data under their own privacy policies.

Google AdMob (advertising, free version)

The free version of the App displays ads served by Google AdMob. To show and measure ads and to prevent fraud, Google may collect and process information such as your device's advertising ID, IP address, approximate location derived from the IP address, device and app information, and your interactions with ads. Depending on your region and choices, ads may be personalised or non-personalised.

Where required by law (for example in the EEA, the UK, Switzerland and certain US states), the App asks for your consent through Google's User Messaging Platform before personalised ads are shown. You can review or change your choice at any time in Settings > Privacy choices (shown when this applies in your region). You can also reset or delete your advertising ID in your Android settings. Learn more: https://policies.google.com/technologies/partner-sites

The free version shows banner and full-screen ads, and may offer optional short videos that you can watch to earn extra NEXO Chat questions or translated pages. Watching is always your choice, and the reward is given only if you watch to the end. Subscribing to NEXO Pro, or being in the 7-day free trial at the start, removes ads from the App.

Google Play (purchases and app integrity)

NEXO Pro subscriptions are sold and processed by Google Play. Google handles your payment information; we receive only the information needed to confirm your subscription, such as the product purchased, the purchase status and a purchase token. The App also includes Google's Firebase App Check and Play Integrity components, which can verify that the App is genuine and unmodified. These do not receive your documents or their content. Learn more: https://policies.google.com/privacy

Google Block Store (free trial date)

Your 7-day free trial starts when you first open the App. So that uninstalling and reinstalling the App does not start a second trial, the App stores one small piece of information, the date the trial started, in Google's Block Store on your device. It contains no document, name, account or other personal information, it is not copied to the cloud or to another phone, and we never receive it. It is removed when you remove the App's data from Block Store or reset your device. If Block Store is not available, the trial simply follows the install date. Learn more: https://developers.google.com/identity/blockstore/android

Google Play app updates (new-version alerts)

Once a day, and when you open the app, NEXO asks Google Play whether a newer version of NEXO is available for your phone, using Google's in-app update library. Google Play answers on your device. If there is one, NEXO may show Google's update prompt and, once per version, a notification. NEXO has no server for this, sends nothing about you, and keeps only the number of the last version it told you about on your device. You can turn the notification off in Settings (New version alerts) or in your phone's notification settings.

Google ML Kit and Google Play services (on-device recognition)

Text recognition, barcode and QR scanning, language detection, the document scanner and translation use Google ML Kit, which processes your images and text on your device. Your documents are not sent to Google for this processing. Language packs and recognition models may be downloaded from Google the first time you use a feature, and Google may collect limited technical information (such as device type, app version and performance metrics) to operate and improve these components. Learn more: https://developers.google.com/ml-kit/terms

Features you choose to use

• Printing: documents you print are sent to the printer you select, over your local network, USB or Bluetooth, or through the Android print service and any printer plug-in you have installed. NEXO also asks the printer for its status and for how your job is going, so that it can tell you the result. When you print from Home you can take a new photo with the camera, choose a photo with Android's photo picker, or choose a file with Android's document picker. NEXO can read only the one item you pick, prints it, and does not add it to your library.
• Web Print: web pages you open are loaded directly from those websites, which receive your IP address and device information as with any browser.
• Sharing and exporting: when you share a file, it goes to the app or destination you choose, under that service's terms.
• Nearby transfer: documents sent to a nearby device travel directly between the two devices over a direct Wi-Fi connection (Wi-Fi Direct), protected by a PIN and end-to-end encryption. They do not pass through our servers. To find the other phone, Android requires the nearby-devices permission (and, on Android 12 and older, the Location permission). NEXO uses this only to connect the two phones; it does not collect, store or send your location.
• Opening PDFs from other apps: if you choose NEXO to open a PDF from another app, NEXO copies it into its private storage and reads it on your device.
• Share as small file and batch sharing: smaller copies and ZIP files are made on your device and are deleted automatically, normally within a day.
• Folder and file sync: if you connect a folder, or pick individual files, on your device, the App reads them to show and index them on your device. While the App is not open, it checks connected folders and files for new or changed ones about every two hours (when the battery is not low) and reads only what is new or changed. If you delete a file from a connected folder, NEXO removes its own copy of that file's text and details at a later check, and keeps it if it has a reminder or a star. You can turn this off with Remove from NEXO when deleted from phone in Settings, then Sync Documents. When you remove a connected folder or file in Sync Documents, NEXO deletes the documents it holds for it and gives back the access Android granted. NEXO never deletes the files you keep on your phone.

6. Permissions the App asks for

The App only asks for permissions when a feature needs them, and you can revoke them at any time in Android settings.

• Camera: to scan documents and QR codes.
• Selected folders and files: to open, import, save and sync documents only in the folders and files you pick with Android's own picker. The App does not request "All files access".
• Notifications: to remind you of due dates and expiring documents.
• Nearby devices / Bluetooth / Wi-Fi: to find and print to nearby printers and to transfer documents to nearby phones.
• Location (Android 12 and older only): Android requires this permission before an app can discover nearby Wi-Fi devices. NEXO asks for it only when you open nearby transfer, and uses it only to find the other phone. It does not read, store or send your location.
• Internet and network state: for ads in the free version, downloading language packs, loading web pages in Web Print and printing over your network. Your documents are not uploaded.
• Run at startup and vibration: to keep your reminders scheduled after a restart and to give feedback when you capture a page.

7. How we protect your information

• Your documents are kept in the App's private storage, which Android encrypts. File managers, the Gallery, other apps and USB file transfer cannot see or copy them; Android blocks this for every app.
• The App can read only the folders and files you choose with Android's own picker. It cannot see the rest of your phone, and you can remove a folder or file at any time in Settings, then Sync Documents.
• You can turn on Biometric Lock (fingerprint, face or screen lock) in Settings.
• Backups you create are encrypted with your password (AES-256) before they are written, so the file is unreadable without it.
• Home-screen widgets you add show your next reminders on your home screen. With Biometric Lock on, the widget shows only how many things are due, not their names or amounts.
• Private data is excluded from cloud backups, and temporary files are cleaned up automatically.
• Nearby transfers are end-to-end encrypted.
• The Privacy Dashboard in the App shows what is stored and what the App can access.

No method of storage or transmission is completely secure, but we design the App so that your documents never have to leave your device.

8. Children

The App is not directed at children under 13, and we do not knowingly collect personal data from children. In India, users under 18 should use the App with the involvement of a parent or guardian. If you believe a child has sent us personal data, contact us and we will delete it.

9. Your rights and choices

Because your documents are stored only on your device, you can view, correct, export and delete them directly in the App at any time. Deleted documents go to the Trash Bin first; to remove one for good, delete it permanently there or empty the Trash Bin. Uninstalling the App deletes all of its private data from your device.

Depending on where you live, you may have rights over personal data we hold about you (for example, support emails):

• India (DPDP Act, 2023): to access a summary of your personal data, to correct, complete, update or erase it, to have grievances redressed and to nominate a person to exercise your rights.
• EEA, UK and Switzerland (GDPR): to access, rectify, erase, restrict or object to processing, to data portability, to withdraw consent at any time and to lodge a complaint with your local data protection authority.
• California and other US states: to know, access, correct and delete personal information, and to opt out of the "sale" or "sharing" of personal information for targeted advertising. We do not sell personal information. For ads in the free version, use Settings > Privacy choices or your Android advertising ID settings.

To exercise any right, email [email protected]. We will respond within 30 days, or sooner where the law requires. We will not discriminate against you for exercising your rights.

10. International processing

Our third-party providers, such as Google, may process data in countries other than your own, including the United States, under their own safeguards. Support emails are handled by our email provider.

11. Changes to this policy

We may update this Privacy Policy when the App or the law changes. We will update the "Last updated" date above and, for significant changes, tell you in the App before they take effect.

12. Contact and grievance redressal

If you have questions, requests or complaints about privacy, contact:

Grievance Officer, NEXO

Email: [email protected]

We acknowledge complaints within 48 hours and aim to resolve them within 30 days.
