Privacy Policy

This Privacy Policy ("Policy") describes the comprehensive policies, procedures, and strict protocols of the Pei Application regarding the collection, use, handling, and protection of Your information. We firmly believe in the principle of absolute client sovereignty, and this legal document reflects Our unwavering, uncompromising commitment to maintaining the highest possible standard of Your privacy.

Interpretation and Definitions

Interpretation

The words of which the initial letter is capitalized have distinct, legally binding meanings defined under the following conditions. The following definitions shall possess the exact same meaning and legal standing regardless of whether they appear in singular or in plural form throughout this Policy.

Definitions

For the exclusive purposes of this Privacy Policy, the following terms are defined as follows:

• Application means the specific software program provided by the Company downloaded by You on any electronic device, officially designated and named "Pei" or "Pei Notes".
• Company (referred to as either "the Company", "We", "Us" or "Our" in this legal Agreement) refers strictly to the developers, owners, and legal entities operating the Pei Application.
• Device means any electronic hardware that can access, download, or run the Application, such as a desktop computer, a mobile cellphone, or a digital tablet.
• Service refers interchangeably to the Application and any features contained therein.
• You (referred to as "You" or "Your") means the individual accessing, downloading, or utilizing the Application, or the company, or other legal entity on behalf of which such individual is accessing or utilizing the Application, as applicable under law.

1. Core Principle: Absolute Client Sovereignty

The fundamental structural architecture of the Pei Application is meticulously built upon the unyielding principle of absolute privacy and digital autonomy. We categorically do not host, store, transfer, intercept, or transmit Your personal writing, private entries, communications, or any user-generated data on external server databases. The Application is designed to operate exclusively within a closed, isolated client-side hardware environment to ensure maximum and unbreakable data confidentiality.

By enforcing this architectural constraint, We ensure that You retain 100% ownership, control, and sovereignty over every single byte of data You input into the Application.

2. Local Database & Data Processing Operations

Strict Offline Functionality

The Application runs entirely and strictly offline on Your personal client-side storage. This means that all algorithmic operations, search functionalities, and data processing related to Your inputs occur exclusively locally on the hardware of Your Device. Your personal entries, structured categories, private messages, and draft items are processed, encrypted, and kept strictly on Your device's physical memory.

Total Absence of External Server Hosting

Unlike conventional software applications, We deliberately do not utilize centralized cloud structures, external servers, or remote databases to sync, back up, or host Your personal files. Because Your data inherently never leaves Your Device—unless You initiate an explicit, manual, and deliberate export action—it remains completely private, secure, and entirely immune from server-side data breaches, remote hacks, or third-party unauthorized server access.

Any backup procedures you choose to undertake are executed entirely within the file systems of Your Device or on personal storage mediums of Your explicit choosing.

3. Crash Diagnostics & Analytics Telemetry Logs

Data Collection for Application Stability

In order to maintain the highest standards of Application stability, debug complex technical anomalies, and ensure a seamless, crash-free user experience, the Application may automatically collect highly specific, anonymous diagnostic logs and crash performance telemetry data (the "Diagnostic Data").

Strict Absence of Personally Identifiable Information (PII)

We guarantee that these crash diagnostics and performance logs are strictly technical and systemic in nature. They do absolutely not contain any Personally Identifiable Information (PII), personal notes, private message contents, passwords, keystrokes, or any sensitive user-generated data. The Diagnostic Data is limited exclusively to technical error codes, memory stack traces at the exact moment of a software failure, and device hardware specifications required to reproduce and fix software bugs.

Absolute Non-Distribution Policy

We maintain a rigorous, strict, and uncompromising legal policy regarding the handling of technical telemetry data. Under no circumstances whatsoever will We ever sell, share, rent, or distribute any technical log statistics, usage patterns, or crash data to external advertising platforms, data brokers, marketing agencies, or unaffiliated third parties.

4. User Responsibilities Regarding Device Security

Because the fundamental design of the Application ensures that all data is stored exclusively and locally on Your hardware, You bear the sole, complete, and ultimate responsibility for maintaining the physical and digital security of Your Device. We strongly advise and explicitly recommend that You utilize robust device-level encryption, secure biometric passcodes, and perform regular, manual backups of Your data using the Application's local export features to prevent unauthorized local access, data corruption, or catastrophic hardware failure.

5. Future Modifications and Updates to this Privacy Policy

We reserve the exclusive legal right to update, amend, or modify this Privacy Policy periodically to reflect necessary changes in technical operations, feature expansions, or shifting international legal requirements. Any and all modifications will be posted prominently within this specific section of the Application and website. Your continued access to, or use of, the Application following the posting of any revisions legally signifies Your explicit acceptance and agreement to the updated Privacy Policy.
