Privacy Policy

BillNest ("BillNest", "the App") is an Android app by Technobi ("Technobi", "we", "us") that helps you track bills and subscriptions, organize them into categories, and receive reminders before they are due. This Privacy Policy explains what information the App handles, where that information lives, and the limited cases in which data leaves your device.

The short version: the bills, subscriptions, and preferences you enter are stored locally on your device. We do not run accounts or upload your financial records to our servers. Data only leaves your device when you take a specific action, such as using AI Smart Import, exporting a backup, showing ads in the free version, or making a purchase through Google Play.

BillNest is designed to work without an account. The information you create in the App is entered by you and saved on your device. This includes:

• Bills you add, such as name, amount, due date, and notes.
• Subscriptions you track, including their renewal dates and billing cycles.
• Categories you create to organize bills and subscriptions.
• Reminder settings, such as when and how far in advance you want to be notified.
• Currency preference used to display amounts.
• Theme preference (for example light, dark, or system).
• Language preference for the App interface.

We do not ask for your name, email address, phone number, or payment card details in order to use the App. Any data processed by third parties (for example advertising identifiers used by Google AdMob) is described in the relevant sections below and is governed by those providers' own policies.

All of the bills, subscriptions, categories, and preferences listed above are stored locally in the App's private storage on your device. This data is not transmitted to Technobi, is not synced to a cloud account we control, and is not visible to us.

This data only leaves your device if you choose to move it, for example by creating a backup or export file and sharing or saving it yourself (see Backup & Export), or by submitting text for AI analysis (see AI Smart Import). If you uninstall the App, its private on-device data is removed by the operating system.

AI Smart Import is an optional feature that helps you turn the text of a bill or subscription into structured entries (such as amount, due date, and biller name) so you do not have to type everything manually. It runs only when you actively trigger it.

The text you submit is transmitted to and processed by Google's Gemini API to return a structured result, which you can review and edit before saving. Google's handling of that request is governed by Google's Privacy Policy and applicable Google AI/Gemini API terms. To avoid sending any text off your device, do not use AI Smart Import and instead add entries manually.

When you import a bill or subscription from an image or a photo, BillNest uses on-device Optical Character Recognition (OCR) to read the text in that image. This OCR step runs locally on your device. The image itself is not uploaded to Technobi or to any third party for OCR.

The text produced by OCR stays on your device unless you then choose to run AI Smart Import, in which case only that extracted text (not the image) is sent to the Gemini API as described above.

BillNest lets you create a backup or export of your data so you can keep a copy or move it to a new device. When you use this feature, a file is generated on your device. You choose what happens to that file, for example saving it to your device storage, a folder you select, or another app or location you send it to.

Because you control where an export or backup goes, any file you create leaves the App's private storage and becomes your responsibility. Technobi does not receive a copy of your backups and does not store them on any server.

BillNest schedules local notifications to remind you about upcoming bills and subscription renewals based on the due dates and reminder settings you enter. These reminders are generated and delivered on your device by the Android system. Their content is derived from your on-device data and is not sent to our servers.

You can control notifications in your Android device settings and within the App. If you disable notifications, reminders will not be shown. See App Permissions for the notification and alarm permissions used to deliver reminders on time.

BillNest may offer home-screen widgets that display information such as upcoming bills or totals. Widgets read from the App's on-device data to render this information on your home screen. Widget content is generated locally and is not transmitted to Technobi. If you add a widget, be aware that the information shown may be visible to anyone who can see your home screen.

BillNest offers optional paid features, including a BillNest Pro subscription and AI Credits. All purchases are processed by Google Play Billing. Technobi does not receive or store your payment card number or full billing details; these are handled by Google.

Google shares with us limited purchase information needed to deliver and validate what you bought (for example whether a purchase or subscription is active). Your use of Google Play Billing is subject to the Google Play Terms of Service and Google's Privacy Policy. Managing, renewing, or canceling a subscription is done through your Google Play account.

The free version of BillNest may show advertisements through Google AdMob. To serve ads, the AdMob SDK may collect and process certain data.

This data is collected and processed by Google LLC under Google's Privacy Policy. Your bills, subscriptions, and other financial data are never shared with AdMob or any advertising network. Where consent is required (for example in the European Economic Area and the United Kingdom), the App presents a consent request using Google's User Messaging Platform, and you can choose between personalized and non-personalized ads. You can also reset or delete your Advertising ID in your Android device settings.

Rewarded Ads

BillNest may offer rewarded ads: optional ads you can choose to watch in exchange for a reward, such as free AI Credits. Watching a rewarded ad is always your choice. When you view a rewarded ad, the same AdMob data described above may be processed by Google to serve and verify the ad. If you do not watch rewarded ads, no reward is granted, but no additional data is processed for that purpose.

AI Credits are a usage allowance that lets you run AI Smart Import a certain number of times. Your credit balance is tracked so the App knows how many AI actions you have available. You can obtain credits as part of a BillNest Pro subscription, receive free credits, or earn them by watching rewarded ads.

Spending an AI Credit is what triggers the AI Smart Import described in section 04, where only your submitted text is sent to the Gemini API. Holding a credit balance by itself does not send any of your data anywhere. The commercial terms of AI Credits (such as expiry and non-transferability) are described in the Terms & Conditions.

We currently do not collect analytics beyond information provided by Google Play or Google AdMob where applicable. In other words, BillNest does not include a separate third-party analytics SDK that profiles your in-app behavior. Google Play may provide us with aggregate, anonymized statistics about installs and crashes, and Google AdMob processes the advertising data described in section 10 for the free version.

If we add analytics in the future, we will update this policy and, where required, request your consent before collecting such data.

BillNest requests only the permissions it needs, and only when a feature requires them. You can grant or revoke permissions at any time in your Android device settings; revoking a permission disables the related feature.

• Camera: used only if you choose to capture a photo of a bill or subscription for import. The captured image is processed on your device by OCR; it is not uploaded for AI processing.
• Notifications: used to deliver bill and subscription reminders on your device.
• Storage / File Picker: used when you import an existing image, or when you create, save, or restore a backup or export file. BillNest accesses only the files you select.
• Internet: used to send text to the Gemini API for AI Smart Import, to load ads in the free version, and to process purchases through Google Play.
• Alarm permissions (such as scheduling exact alarms): used so that reminders can fire at the correct time even when the device is idle.

BillNest does not request location, contacts, or microphone permissions.

We do not share the contents of your bills, subscriptions, or categories with third parties for their own marketing. Data leaves your device only in the specific, user-initiated situations described in this policy: text you submit to the Gemini API for AI Smart Import, files you export yourself, purchases you make through Google Play Billing, and the advertising data processed by Google AdMob in the free version.

BillNest relies on the following third-party services, each governed by its own terms and privacy policy:

• Google Play Services, for core app functionality and delivery on Android.
• Google Play Billing, for BillNest Pro and AI Credit purchases.
• Google AdMob, for advertising in the free version, including rewarded ads.
• Google Gemini API, for processing text you submit through AI Smart Import.

These services are operated by Google LLC under Google's Privacy Policy. We do not use social media login SDKs, and we do not share your on-device financial records with any of these services beyond what each feature explicitly requires.

BillNest is a general-purpose finance utility intended for a general audience and is not directed at children under 13, or under the equivalent minimum age in your jurisdiction. We do not knowingly collect personal information from children. If you believe a child has provided information through the App, or if you are a parent or guardian with questions, please contact us at the email in section 22 and we will address it.

Because your bills, subscriptions, and preferences are stored in the App's private storage on your device rather than on our servers, they are not exposed to server-side breaches of Technobi. Data transmitted for AI Smart Import, ads, and purchases is sent over encrypted connections (HTTPS/TLS) to Google.

No method of storage or transmission is completely secure. We encourage you to protect your device with a screen lock, keep your operating system up to date, and keep your own copies of important information. Any backup or export file you create is under your control and should be stored securely.

Depending on where you live, you may have rights under laws such as the EU/UK General Data Protection Regulation (GDPR) or similar regulations, including rights to access, correct, delete, or restrict processing of your personal data. Because BillNest stores your data on your own device, you can exercise most of these directly:

• Access and edit: view and change your bills, subscriptions, categories, and preferences at any time in the App.
• Delete: delete individual entries in the App, or uninstall the App to remove its on-device data.
• Export: create a backup or export file to obtain a copy of your data.
• Ad choices: manage personalized ads through the in-app consent options and reset your Advertising ID in Android Settings → Google → Ads.
• Permissions: grant or revoke Camera, Notifications, Storage, and Alarm permissions in your device settings.

For requests concerning data processed by Google (for example advertising or Gemini API requests), you may also contact Google or use Google's privacy controls. To reach us about your rights, use the contact details in section 22.

Your bills, subscriptions, categories, and preferences are retained on your device for as long as the App is installed and you keep them. You control retention: deleting entries removes them, and uninstalling the App removes its private on-device data. Backup or export files you created remain wherever you saved them until you delete them.

Text submitted to the Gemini API is processed to return a result; its retention by Google is governed by Google's applicable terms and privacy policy. Advertising and purchase data are retained by Google according to Google's policies.

BillNest is available to users internationally. Your on-device data stays on your device wherever you are. When you use features that contact Google (AI Smart Import, ads, or purchases), your request may be processed by Google on servers located in other countries, including outside your own. By using those features, you understand that the associated data is handled by Google under Google's global infrastructure and policies. We rely on Google's safeguards for any such international transfers.

We may update this Privacy Policy from time to time to reflect changes to the App, our practices, or legal requirements. When we make changes, we will revise the "Last updated" date at the top of this page and, where appropriate, note the change in an app update. Significant changes may be highlighted in the App. We encourage you to review this page periodically.
