1. Introduction

Welcome to our Privacy Policy. Your privacy is critically important to us. This Privacy Policy document contains types of information that is collected and recorded by our services and how we use it.

2. Information We Collect

We collect information that you provide directly to us, including:

• To notify you about changes to our service
• To provide customer support
• To gather analysis or valuable information to improve our service

4. Data Security

The security of your data is important to us but remember that no method of transmission over the Internet or method of electronic storage is 100% secure. While we strive to use commercially acceptable means to protect your personal information, we cannot guarantee its absolute security.

8. GrammarFix: Local and Optional Cloud AI

GrammarFix selects on-device AI by default. Optional Cloud AI sends submitted text for correction, rewriting, translation or drafting to App City Studios and OpenAI. Chat includes recent conversation context. Cloud editing suggestions send the current rewrite draft. Enabled personalization includes saved background and writing instructions. Ordinary typing does not automatically send AI requests. Switch back to on-device AI in Settings to stop future cloud requests.

The keyboard needs iOS Allow Full Access for network requests. Full Access alone does not select Cloud AI. On-device corrections remain local. Preferences, custom presets, personalization and daily free-chat counts are stored locally on your device. Purchases are processed by Apple; we use StoreKit to check Premium entitlement and do not receive payment details.

Our GrammarFix endpoint processes text to return AI results. Its application code does not log submitted text or generated responses. Requests tell OpenAI not to store completions for later API retrieval; this does not disable abuse-monitoring retention. Under OpenAI's standard API policy, prompts and responses may be retained for up to 30 days for abuse monitoring, with longer retention where required by law or necessary for safety.

The service uses IP-based rate limits and short-lived usage counters to control abuse and costs. Per-IP counters remain in server memory until expiry cleanup or an instance restart. Hosting and AI providers process network metadata needed to operate their services, subject to their applicable policies. We do not use submitted text or counters for advertising or cross-app tracking. Avoid submitting personal information about children unnecessarily.

9. Zero and Stand & Hydrate: Optional Ad Measurement

Zero: Debt Payoff Planner and Stand & Hydrate keep their private app records on the device. They offer optional Meta advertising measurement to help us understand which advertisements lead to installs and app opens. The Meta SDK is initialized only after iOS tracking permission is granted. Any previously saved in-app opt-out is also respected.

With permission, Meta may process an advertising identifier, an app-specific anonymous identifier, app launch/session activity, and technical device/network information, such as device model, operating-system version, app version and IP address. The SDK may also process technical diagnostics according to its own privacy disclosures. Meta processes this information under its applicable policies, available at Meta's Privacy Policy.

We do not send debt names, balances, payment amounts, hydration logs, health/profile details, saved locations or purchase events to Meta through this integration. You can decline the iOS tracking request without losing app functionality, or revoke tracking permission in iOS Settings under Privacy & Security > Tracking. Earlier app versions also offer an in-app measurement control. Revoking permission stops new app activation events; requests already sent or in flight cannot be recalled. A fresh app launch without tracking permission does not initialize the Meta SDK.

Separately, Apple's SKAdNetwork may report anonymous install attribution to the advertising network. The app supplies only the fixed install value 0, not financial, health, location or purchase data. Apple's signed postbacks do not contain user- or device-specific information and operate independently of the Meta setting and ATT permission.
