ThumbType

1. What ThumbType Does

ThumbType is a custom Android keyboard (Input Method Editor / IME) developed by Dumb Donkey. It includes the following features:

• Custom Keyboard: A full replacement keyboard for typing on Android devices.
• AI Brain (Optional): Rewrites typed text using OpenAI's API. Requires you to supply your own OpenAI API key.
• Voice Typing: Converts spoken words to text using Android's built-in speech recognition.
• Contact Capture: Lets you scan QR codes or speak contact details to quickly save new contacts to your device address book.
• Send Module / Contact Library: Displays your device contacts inside the keyboard for quick selection while composing messages.
• Address Book: A local on-device contact manager within the app.
• QR Code Creator: Generates QR codes locally on your device.
• Notepad: A local notepad for drafting text.
• Launchpad: A quick-access launcher for sharing files (photos, documents, audio).

2. Data We Collect — None

We do not collect:

• Text you type
• Messages you compose or send
• Your contacts or contact information
• Your API keys
• Your name, email address, or account information
• Device identifiers or advertising IDs
• Location data
• Usage statistics or analytics
• Crash or diagnostic reports

There are no analytics SDKs, no crash reporting libraries, no advertising SDKs, and no Dumb Donkey backend servers in this application.

3. Keyboard & Input Method Access

What ThumbType does with typed text

• Standard keyboard function: Typed characters are sent to the app you are currently typing in. This is the normal, expected behavior of any keyboard.
• AI rewriting (only when you tap the robot button): If you have set up the AI Brain feature and you explicitly tap the robot button, the text currently in the input field is sent directly to OpenAI using your own API key. This transmission goes directly from your device to OpenAI — it does not pass through Dumb Donkey.

What ThumbType does NOT do with typed text

• We do not record, log, or store any text you type.
• We do not transmit your typing to Dumb Donkey or any Dumb Donkey server.
• We do not monitor, analyze, or profile your typing patterns.
• Text is never sent to any AI provider unless you explicitly trigger it by tapping the AI button.
• Password fields are handled by Android's system-level protections; ThumbType respects these flags and does not process text from password fields.

4. AI Brain Feature & Third-Party AI Providers

The AI Brain feature is entirely optional. You can use ThumbType as a full-featured keyboard without ever setting up AI Brain.

How AI Brain works

1. You create your own account directly with OpenAI.
2. You obtain an API key from OpenAI and enter it in ThumbType's AI Brain settings.
3. Your API key is stored locally on your device only.
4. When you tap the robot button, the text in the current input field is sent directly from your device to your chosen provider's API endpoint.
5. The AI provider returns a rewritten version of the text, which ThumbType inserts back into the input field.

Billing and charges

Any costs or charges associated with AI API usage are between you and your chosen provider. Dumb Donkey does not receive payment and is not responsible for any charges you incur.

5. Contacts Access

ThumbType requests two contacts-related permissions: READ_CONTACTS and WRITE_CONTACTS.

READ_CONTACTS — Send Module & Contact Library

Reads your device contacts to display them inside the keyboard for quick recipient selection. Your contacts are never transmitted off your device by Dumb Donkey.

WRITE_CONTACTS — Contact Capture

Allows the Contact Capture feature to save a newly captured contact to your device's local contacts app. This data is never transmitted to Dumb Donkey.

Both permissions are requested at runtime and can be denied without affecting core keyboard functionality.

6. Microphone & Voice Input

ThumbType requests the RECORD_AUDIO permission for voice typing. Audio is processed on your device — nothing is sent to Dumb Donkey. The microphone is not accessed passively or in the background.

7. Local On-Device Storage

ThumbType stores the following data locally on your device only. None of this data is transmitted to Dumb Donkey.

• AI API Keys: Stored in private SharedPreferences, sandboxed to the ThumbType app.
• Keyboard Settings: Your skin, color preferences, and layout customizations.
• Address Book: Contact records added in the app's built-in address book.
• Personal Dictionary: Words you have added or that were auto-learned. Never transmitted anywhere.
• Notepad Content: Text notes you create. Stored locally only.

All locally stored data can be deleted by clearing the app's data or uninstalling the app.

10. Children's Privacy

ThumbType is not directed at children under the age of 13. We do not knowingly collect personal information from children under 13. If you are a parent or guardian and believe your child has provided personal information to us, please contact us below.

11. Security

• API keys are stored in Android's private SharedPreferences, sandboxed to the ThumbType app.
• All communications to AI providers use HTTPS (TLS encryption).
• Dumb Donkey does not operate any cloud servers or databases, eliminating server-side data breach risk.
