Privacy Policy — TextHook

Last updated: 24 April 2026

1. Who We Are

TextHook is developed and operated by Narrative Systems Ltd ("we", "us"). For any questions or requests about this privacy policy, contact us at texthook@narratem.com.

2. Data We Access On Your Device

TextHook accesses the following data on your device solely to provide its core forwarding functionality:

• Incoming SMS messages — the message body and the sender's phone number, to evaluate whether they match filter rules you have configured.
• Contact display names — looked up locally on your device when you configure a rule that matches by contact name (Pro feature). Contact data is not stored beyond the match operation.
• Notification permission — used to show an ongoing notification letting you know TextHook is listening for incoming SMS. This is a transparency signal only; TextHook does not run a foreground service.

TextHook does not read your SMS history, sent messages, draft messages, or any messages that do not match a rule you have configured.

3. What Is Transmitted Off Your Device, To Whom, and When

When an incoming SMS matches a filter rule you have configured, TextHook transmits the following data to the HTTP webhook URL you explicitly specified in the app:

• The SMS message body
• The sender's phone number
• The contact display name associated with the sender (only if your rule is configured to include it — Pro feature)
• The timestamp of the message

This data is sent only to the URLs you have entered in TextHook. You are responsible for the privacy and security practices of those endpoints. TextHook has no influence over, and is not responsible for, how third-party webhook services handle your data.

4. TextHook Has No Servers

TextHook does not operate any servers or backend infrastructure. No SMS content, phone numbers, or personal data is ever sent to us. All data processing occurs on your device, and all forwarded data goes only to endpoints you have configured.

5. Third-Party Services Within the App

• Google Play Billing — used to process the optional one-time Pro upgrade purchase. Purchase data is handled entirely by Google. See Google's Privacy Policy.

TextHook does not include any analytics, crash-reporting, or advertising SDKs.

6. On-Device Data Retention

TextHook keeps a local log of forwarding activity (which rules matched and whether the webhook call succeeded). Free users' logs are retained for 7 days. Pro users can configure retention between 1 and 90 days. Logs are stored only on your device and are never uploaded to us.

Pending retries (queued forwards waiting for a network connection) are automatically discarded after 7 days if undelivered.

7. Children

TextHook is not directed at children under the age of 13. We do not knowingly collect any information from children. If you believe a child has used the app, contact us and we will assist with data deletion.

8. Your Rights and How to Delete Your Data

Your data stays on your device. You can remove it at any time:

• In-app: Settings → Delete all data. This permanently wipes all rules, webhooks, logs, and preferences from your device.
• Uninstall: uninstalling the app removes all local data.

TextHook runs no servers and keeps no copy of your data, so there is nothing held on our side to delete on request. For any privacy questions, contact texthook@narratem.com.

As a UK resident, you have rights under the UK GDPR and Data Protection Act 2018, including rights of access, rectification, erasure, restriction, portability, and objection. To exercise any of these rights, contact us at the email above.

9. Data Security

• In transit: all webhook calls use HTTPS. Cleartext HTTP is not permitted.
• At rest: webhook authentication headers and secrets are encrypted using AES-256-GCM via the Android Keystore. Your data never leaves the device in unencrypted form.

10. Changes to This Policy

If we make material changes to this policy, we will update the "Last updated" date above. We recommend checking this page periodically. Continued use of the app after a change constitutes acceptance of the updated policy.

11. Contact and Complaints

For privacy questions, data-deletion requests, or any complaints, contact: texthook@narratem.com.

If you are not satisfied with our response, you have the right to lodge a complaint with the UK Information Commissioner's Office (ICO) at ico.org.uk or by calling 0303 123 1113.
