Why Data Portability Matters for a Recording Tool
When managing a pottery practice, the value of a record lies in its longevity. Over years of working in a studio, a potter accumulates a vast archive of material tests, firing schedules, and work histories. In the design of modern recording tools, “local-first” storage has become a significant technical choice. This means that the data—including every glaze recipe and firing log—is stored directly on the user’s device rather than on a central cloud server.
While local storage offers advantages in terms of privacy and offline access, it introduces a critical requirement for data portability. Without a robust backup plan, the loss of a device or a move to a new phone could result in the loss of years of irreplaceable studio history. Data portability ensures that the user, not the app developer, remains the true owner of their information. A recording tool should provide clear pathways to move that data into other formats, allowing for external backups or transition between devices.
The Three Export Formats
To accommodate different needs—from technical analysis to full system backups—a well-designed recording system offers multiple export formats. Understanding what each format is specifically for allows a user to choose the right tool for their immediate situation.
| Export Format | Content Included | Primary Use Case |
|---|---|---|
| CSV | A spreadsheet-compatible list of works and firing processes, including tags, status, and firing temperatures. | Best for quick reviews, sorting data in a spreadsheet, or performing technical analysis of firing trends. |
| Photo-included ZIP | A comprehensive backup encompassing works, process logs, glaze masters, and all associated photos. | The gold standard for full backups; essential when moving records to a new device or creating a permanent studio archive. |
| A formatted document with exactly one page per work, including a photo thumbnail, basic info, and process details. | Ideal for sharing a single-page summary with a gallery, a teacher, or printing a physical copy for a studio binder. |
When an export is initiated, the app utilizes the standard share sheet on the device. This allows the user to send the generated files directly to their preferred destination, such as an email account or a local “Files” folder, ensuring the information is stored safely outside of the app environment.
How Import and Restore Works
Restoring data is a straightforward process, but the outcome depends heavily on the file type selected. Import can be performed using either a CSV or a ZIP file, accessed via a file picker.
A critical distinction exists between these two methods regarding visual data. While a CSV file effectively restores text-based records, it does not contain the binary data required to restore images. Consequently, importing from a CSV file alone does not restore photos; only a ZIP file can restore both the records and the associated photos simultaneously.
To prevent accidental data duplication or errors, the system is designed with a safety step. Before any data is added to the database, a confirmation dialog appears displaying the exact count of records to be imported. This transparency allows the user to verify the backup file before completing the process.
Our Philosophy on Free Data Ownership
We believe that foundational recording and the right to own one’s data should never be locked behind a paywall. While specialized analysis tools or unlimited work registrations are part of our Pro tier, the ability to export and import data in CSV, ZIP, and PDF formats is provided entirely for free.
This approach is rooted in a commitment to data ownership. It is common for subscription-based tools in this category to gate export behind a paid tier, which can leave a user’s own records tied to an ongoing subscription. By providing these tools for free, we ensure that every user has the means to back up their history and maintain their records long-term, regardless of their subscription status.
Maintaining Your Records Across Updates
Questions often arise regarding whether app updates risk the integrity of existing records. The database for KilnNote is specifically designed with a migration strategy that preserves all existing data whenever an update is installed. While the technical structure of the database is built for permanence, we still recommend as a matter of good practice that users perform periodic ZIP backups. This routine ensures that even in the event of hardware failure or device loss, your studio’s history remains intact.
How KilnNote Handles Data
KilnNote provides all the export and import functions mentioned above—CSV, PDF, and photo-included ZIP—as free features accessible from the settings menu. Our Pro tier, available as a one-time purchase, removes the registration limit for works and adds advanced analysis tools like board views and comparison sliders, but it never restricts your ability to export your data.

Summary
A recording system is only as strong as its backup plan. By utilizing CSV for analysis, PDF for sharing, and ZIP for full photo-included backups, you can ensure your pottery history is portable and secure. True data ownership means having the freedom to move and restore your records at any time, a foundation we provide as a core part of our studio management philosophy.
