Plaintext Data Storage

With the turnover of digital note-taking software, many users are facing the risk of “data hostage”: reliance on cloud servers, encountering proprietary database format encryption, and vendors discontinuing updates, making data impossible to export.

We firmly believe that data ownership should belong entirely to the user. Through the technical architecture of “all-plaintext storage,” your digital assets will gain true independence and perpetuity.

Why Choose All-Plaintext Storage?

1. Standardized Note Format: HTML as the Core

Although Markdown is widely popular, it suffers from pain points like non-unified syntax standards, numerous dialects, and inconsistent cross-platform rendering.

• Seamless cross-platform: We default to storing notes in HTML format. As the underlying standard of the Web, HTML has decades of backward compatibility, and any operating system, any browser, can parse it perfectly.
• Richer functional expression: Compared to Markdown, HTML natively supports more complex layouts, multimedia embedding, and interactive components, without relying on specific plugins from specific software.

2. Multimodal Lightweight Data Structures (.toml / .tsv / .jsonl)

For different data scenarios, we adopt the most suitable plaintext format for storage, balancing “human readability” and “machine parsability”:

• Configuration and metadata (.toml): Uses the clearly structured TOML format to store application settings and note properties, easy to read and write.
• Structured tables and lists (.tsv): Compared to CSV, TSV avoids comma conflict issues and can be easily edited and counted with a text editor.
• Ledger and log records (.jsonl): Uses the line-delimited JSON format (JSON Lines), suitable for appending high-frequency dynamic records and conducive to streaming processing of large data volumes.

3. Naturally Adapted to Version Control and Local Ecosystems

Because all data is plaintext, you unlock a degree of freedom that proprietary formats cannot match:

• Version control (Git-friendly): You can directly use Git for version control of your note directory, with every single line modification clearly visible, completely saying goodbye to the anxiety of accidental deletion and overwriting.
• Seamless ecosystem integration: You can freely use your system’s built-in search tools (such as Mac Spotlight, Windows Search) or command-line tools (like grep) to perform instant global searches of note content without opening any specific software.

A Digital Asset That Lasts a Lifetime

All-plaintext storage is not just a technical choice, but also an attitude of responsibility toward one’s digital legacy. It means you can fully back up your data to anywhere (cloud drive, local hard drive, or NAS) at any time, and even one day in the future, completely leave our software behind and continue reading and writing your lifelong knowledge base with the most basic text editor.

Plaintext Storage and Performance Improvement

When massive files exist, pure plaintext storage can cause disk I/O to be extremely time-consuming. To address this, Easchi supports using a database to cache data, thereby greatly improving query efficiency.
