Privacy Policy

Ardhi Smart Meter is a prepaid / smart electricity metering platform that connects customer mobile apps, field meters, payment providers, and utility operations tools. For privacy questions, contact us at support@codegraphics.co.tz or via the contact details published on arusmartmeter.codegraphics.co.tz.

We may collect the following categories of information:

• Account details: name, email address, phone number, meter number, and authentication credentials (including optional SMS one-time codes for login / two-factor authentication).
• Payment and top-up data: amount, payer mobile money number, transaction / order identifiers, tariff-related estimates, and payment status from our payment partners (for example mobile money gateways). We do not store your full mobile money PIN.
• Meter and usage data: remaining credit (kWh), power draw, telemetry timestamps, optional per-circuit readings, switch / load commands, remote cutoff status, and related device logs needed to operate prepaid metering.
• App and device data: app version, device type, language preference, notification tokens (where you allow push notifications), and basic diagnostic logs to keep the Service reliable and secure.
• Support communications: messages you send to support, including chat with in-app advisors such as Lita when you choose to use them.

• Provide prepaid top-up, token / credit delivery, and meter monitoring.
• Authenticate users, protect accounts, and send SMS alerts (for example OTP, payment receipt, low balance, or switch change notices).
• Show usage analytics, forecasts, and operational insights in the customer app and utility dashboard.
• Detect fraud, abuse, faults, or anomalous consumption patterns to protect customers and the utility.
• Improve reliability, security, and customer support.
• Comply with applicable law and respond to lawful requests from competent authorities.

We process personal data to perform the Service you request (contract), to operate secure metering and payments (legitimate interests balanced against your rights), and where required by law. Where consent is needed (for example certain marketing messages or optional device permissions such as camera for meter QR scan), you may withdraw consent where the law allows, without affecting prior lawful processing.

We may share information with:

• Payment processors and mobile money providers to complete top-ups.
• SMS gateway providers to deliver OTP, receipts, and service alerts.
• Hosting, cloud, and infrastructure providers that process data on our instructions.
• Utility / admin operators using the dashboard to manage meters, customers, and service actions.
• Professional advisers or authorities when required by law or to protect rights and safety.

We do not sell your personal information.

Data may be processed on servers in Tanzania or other locations used by our hosting and service partners. Where data leaves Tanzania, we take reasonable steps to protect it consistent with this Policy and applicable requirements.

We keep account, payment, meter telemetry, and audit logs for as long as needed to provide the Service, resolve disputes, meet legal / accounting obligations, and maintain security. When data is no longer required, we delete or anonymise it where practical.

We use industry-standard safeguards such as encrypted transport (HTTPS), authenticated APIs, access controls for admin tools, and optional SMS two-factor authentication. No system is perfectly secure; please protect your phone, OTP codes, and account credentials.

Subject to applicable law, you may request access to, correction of, or deletion of certain personal data, or raise a complaint about our handling of your information. Contact support@codegraphics.co.tz. Some meter and payment records may need to be retained for regulatory, fraud-prevention, or accounting reasons.

The Service is intended for adult account holders and authorised utility customers. We do not knowingly collect personal data from children for marketing purposes.

We may update this Policy from time to time. The "Last updated" date at the top will change when we do. Continued use of the Service after an update means you accept the revised Policy.
