Frequently asked questions
Is my text saved on a server?
No. Your text is saved only in this browser (localStorage) and is never sent to a server.
Can I see it on other devices?
It saves only in this browser, so it won't appear on other devices or browsers. If needed, save it as text and move it.
What happens if I clear my browser data?
Clearing your browser storage also deletes the memo. Download important notes as a file to keep them.
Practical example and verification criteria
Online Notepad: First distinguish whether you need calculation, recording, timing, audio, or a screen check, then set units, intervals, repetitions, volume, and storage options for the real environment. Locally saved data may exist only in the current browser and device and can disappear when browser data is cleared, private mode is used, or the device changes.
Online Notepad: For a quick check, start with 1 note → export JSON → import as a small input whose result relationship you can verify directly. Confirm that the input summary, units, and options match your intent before applying the tool to real values or a copy of the source; this reduces setup mistakes.
Online Notepad: Before relying on a timer or alert, test sound, volume, screen lock, and background behavior over a short interval, and also register important schedules in an operating-system alarm. Reopen exported files to verify saved results. Audio and screen results depend on hearing, ambient light, and device settings and do not replace professional measurement or long-term storage.
Online Notepad · Work record: For real work, record the input conditions, selected options, and result together. Do not assume the same state will remain after a refresh or device change. Preserve important results separately using copy, download, a screenshot, or another method the page supports, then reopen them in the target environment.
Online Notepad · Error check: If an error or unexpected result appears, reduce the input, run again with default options, and then change one condition at a time. Recording error messages and boundary values helps distinguish format issues, unsupported cases, and browser resource limits, and prevents an empty result from being mistaken for success.
Online Notepad · Scope of use: Check the page guidance for browser processing versus server lookup, storage location, and supported scope. Use sensitive source material or secrets only when strictly necessary. High-impact work such as legal, financial, or medical decisions or changes to an operational system requires current authoritative information and a separate verification process.
