TOWO Privacy Policy
Effective Date: October 20, 2026
TOWO is a translation and writing-assistance keyboard application operated by Kean Hui Lim (“TOWO,” “we,” “us,” or “our”).
This Privacy Policy explains what information TOWO processes, when information may leave your device, how it is used, and the choices available to you.
1. Information TOWO Processes
TOWO is designed to process text only when needed to provide features that you intentionally use.
Translate
When you tap Translate, the text you choose is sent to TOWO’s servers. TOWO uses OpenAI to generate the translation. The request also includes the selected language direction.
This version of TOWO does not use Apple on-device translation for Translate.
Natural Rewrite and Professional Rewrite
When you tap Natural or Professional, the text you choose is sent to TOWO’s servers. TOWO uses OpenAI to generate the rewrite.
The app currently allows up to 3 successful Professional rewrites per local calendar day. That count is stored on your device. TOWO’s servers also enforce per-installation, per-network, global, and monthly usage limits. A server limit can refuse a request even when local Professional allowance remains.
Natural Rewrite does not use the local Professional daily count. It is still an online AI feature and is subject to server limits.
Paste and Incoming Messages
When you use TOWO’s Paste feature, TOWO accesses clipboard text only after you choose that feature, only when the keyboard has the access required by iOS, and only if you have allowed online AI features.
TOWO does not continuously monitor your clipboard.
If you use Paste to translate incoming text, the selected clipboard text is sent for translation in the same manner as other Translate requests.
2. What TOWO Does Not Intentionally Transmit
Simply enabling or using the TOWO keyboard does not cause TOWO to transmit everything you type.
Ordinary keyboard actions such as typing letters, numbers, symbols, spaces, returns, deleting text, and inserting emoji are handled on the device and are not intentionally sent to TOWO’s backend.
Recent emoji selections are stored locally to provide the Recent emoji feature.
Pinyin displayed with supported Chinese results is generated on the device. Pinyin is provided as a reading aid and is not inserted when you choose to insert only the translated or rewritten text.
TOWO does not upload keystrokes, clipboard contents, or field text merely because Full Access is enabled or because online AI permission has been granted. Text leaves the device only when you tap Translate, Natural, Professional, or Paste-to-translate, and only if those features are permitted.
3. Full Access and Online AI Permission
Apple requires third-party keyboards to have Allow Full Access enabled for functionality that needs network communication.
TOWO’s online features — Translate, Natural Rewrite, Professional Rewrite, and Paste-to-translate — require Full Access.
Full Access is an iOS keyboard permission. It is not permission to send your text to OpenAI.
Before the first online AI request, TOWO asks for your permission and explains that selected text is sent to TOWO’s servers for processing by OpenAI. It also explains that a random installation identifier is transmitted and that TOWO’s servers may store protected hashes of the identifier and network address for abuse prevention and usage limits.
If you choose Don’t Allow, or if you have not chosen yet, those requests are not sent. You can change this choice later in the TOWO app under Online AI features.
You can use ordinary keyboard functionality without using TOWO’s online translation or writing features, and without allowing online AI features.
4. How Submitted Text Is Processed
When you tap Translate, Natural, Professional, or Paste-to-translate after allowing online AI features, TOWO sends the text needed to fulfill that request to TOWO’s servers.
TOWO’s servers send that text to OpenAI to generate the translation or rewrite.
TOWO’s current implementation requests that OpenAI not store generated responses for later retrieval by TOWO by using the applicable API storage setting. This is not a guarantee that OpenAI never retains or processes submitted information for security, abuse prevention, legal, or operational purposes under OpenAI’s policies.
TOWO does not store the text of your translation or rewrite in TOWO’s SQLite usage database. TOWO’s application code does not intentionally create a message history of the text you submit.
Infrastructure providers, including Render and Cloudflare, may process technical request information such as IP addresses, timestamps, request paths, response status information, and similar operational metadata needed to provide, secure, and maintain the service. TOWO cannot promise that those providers retain no information.
5. Information Stored Locally
TOWO stores limited information on your device to provide app and keyboard functionality. This may include:
- translation preferences;
- onboarding status;
- recent emoji selections;
- Professional Rewrite usage count and reset information;
- Professional entitlement information used by the app;
- your online AI permission choice; and
- information needed for the app and keyboard to share settings and determine feature availability.
This information is primarily used locally for TOWO functionality. TOWO does not require you to create a TOWO user account for the current version of the service.
5.1 Installation Identifier, Network Address, and Usage Limits
Individual authorized request records in TOWO’s usage database are generally deleted after approximately 48 hours.
To help diagnose usage-limit issues, prevent abuse, and evaluate whether usage limits are appropriate, TOWO also records limited information about requests rejected by its usage protections. These records may include protected hashes of installation identifiers and network addresses, the feature requested, the limit reached, timestamps, and retry information. These records are generally retained for up to 14 days.
TOWO may retain aggregated daily usage and limit statistics for up to 90 days. These aggregated records do not contain installation identifiers, network addresses, or their hashes.
Monthly token totals may be retained for usage accounting and cost control. These retention periods do not describe or limit information retained independently by OpenAI, Render, Cloudflare, or other infrastructure providers under their respective policies.
6. Analytics, Advertising, and Tracking
TOWO does not currently include third-party advertising or analytics SDKs for tracking your activity.
TOWO uses limited first-party operational analytics to understand service usage, identify when usage limits are reached, investigate technical issues, and evaluate whether its usage limits should be adjusted. These analytics use technical request information rather than the contents of submitted translations or rewrites.
TOWO does not use these operational analytics for advertising or cross-app tracking.
TOWO does not use submitted text for targeted advertising.
TOWO does not currently sell personal information.
7. Third-Party Service Providers
TOWO relies on third-party providers to operate certain features. These currently include:
OpenAI — processes the text you choose to Translate, rewrite with Natural Rewrite, or rewrite with Professional Rewrite.
Render — hosts TOWO’s backend service.
Cloudflare — provides related hosting and network infrastructure in front of that service.
Apple — provides the iOS platform, keyboard-extension environment, distribution services, and related system functionality.
These providers may process information according to their own terms and privacy policies, including technical metadata such as IP addresses. TOWO cannot control or promise their retention practices.
8. Data Security
We use reasonable technical measures intended to protect information transmitted through TOWO. However, no method of electronic transmission, processing, or storage can be guaranteed to be completely secure.
Do not submit highly sensitive information through TOWO if you are not comfortable having that information processed by the services required to provide the requested feature.
9. Children’s Privacy
TOWO is not specifically directed to children under 13, and we do not knowingly seek to collect personal information from children under 13.
If you believe a child has provided personal information to TOWO inappropriately, contact us using the information below.
10. Your Choices
You control whether to allow online AI features and whether to use Translate, Natural Rewrite, Professional Rewrite, or Paste-to-translate.
You may withdraw online AI permission in the TOWO app. Withdrawal stops later Translate, Natural Rewrite, Professional Rewrite, and Paste-to-translate requests. It does not turn off ordinary typing.
You may also disable TOWO, disable Full Access, or uninstall the app through iOS.
11. Changes to This Privacy Policy
We may update this Privacy Policy as TOWO changes.
If we make material changes, we may update the effective date or provide other notice where appropriate. Your continued use of TOWO after an updated policy becomes effective is subject to the updated policy.
