Privacy Policy

Last updated: 7 October 2026

This Privacy Policy explains how Fetch Technology Pte Ltd (UEN 201729678R, Singapore) — "we", "us", "our" — handles information in the Tempo mobile application ("the App"), which pairs with the CASEL Tempo temperature patch. We are committed to protecting your privacy and comply with Singapore's Personal Data Protection Act (PDPA).

In short: Your temperature readings stay on your phone. Nothing is sent off your device unless you turn on the optional Remote Monitoring feature — and even then the data is encrypted and relayed only to the phone you choose. We show no ads, run no analytics, and never sell your data.

1. Information we process

Health and temperature data

When connected to a Tempo patch, the App records body-temperature readings and their timestamps, and lets you store alert thresholds, calibration values, and profile names you enter. This information is stored locally on your device (in the App's private storage) and is not transmitted to us during normal use.

Bluetooth and device connection

The App connects to your Tempo patch over Bluetooth Low Energy to receive readings and battery status. It does not scan for, connect to, or collect information about any other devices around you.

Remote Monitoring (optional)

If you choose to enable Remote Monitoring (Bridge / Receiver mode), the "bridge" phone relays temperature readings, battery level, and connection status to your paired "receiver" phone. This relay uses Google Firebase (Realtime Database and Anonymous Authentication) as our cloud infrastructure. In this mode:

Reading payloads are encrypted on your device (AES-GCM) before transmission and sent over an encrypted (TLS) connection.
Authentication is anonymous — no name, email, phone number, or account is created or required. A random identifier links your two paired phones.
Relayed data is transient and used only to display current readings on your receiver phone.

Permissions we request

Bluetooth — to find and connect to your Tempo patch.
Location (fine) — required by older versions of Android solely to permit Bluetooth scanning. The App is flagged neverForLocation and does not derive, collect, or use your physical location.
Notifications — to alert you when temperature crosses a limit you set, and to show ongoing monitoring status.
Foreground service / ignore battery optimizations — to keep monitoring reliably while the App is in the background.
Internet / network state — used only for the optional Remote Monitoring relay.

2. How we use information

We use the information above only to provide the App's features: displaying and charting your readings, storing history, triggering the alerts you configure, calibrating against your own thermometer, and — if enabled — relaying readings to your chosen receiver phone. We do not use it for advertising or profiling.

3. Sharing and disclosure

We do not sell your data and do not share it with third parties for their own purposes. Data processed through Remote Monitoring passes through Google Firebase purely as our hosting provider (a data processor acting on our behalf). We may disclose information if required by law.

4. Data retention and deletion

Readings and settings stored locally remain on your device until you delete them in the App or uninstall it. Data relayed through Remote Monitoring is transient and is not retained for long-term storage by us. To request deletion of any data associated with your use of Remote Monitoring, contact us at the address below.

5. Security

Remote Monitoring payloads are encrypted on-device with AES-GCM and transmitted over TLS. Locally stored data is held in the App's private, sandboxed storage. No method of transmission or storage is completely secure, but we take reasonable measures to protect your information.

6. Children

The App is intended for use by adults to monitor themselves or those in their care. It is not directed to children, and we do not knowingly collect personal data from children.

7. Medical disclaimer

Tempo is a wellness and monitoring tool. It is not a substitute for professional medical advice, diagnosis, or treatment. Always consult a qualified healthcare provider about any health concern or before making decisions based on a reading.

8. Your rights

Under the PDPA you may request access to, or correction or deletion of, personal data we hold about you. Contact us using the details below and we will respond in accordance with applicable law.

9. Changes to this policy

We may update this policy from time to time. Material changes will be reflected by the "Last updated" date above.
