Storing notes in Markdown with front‑matter or simple headings keeps them future‑proof, diff‑friendly, and easily searchable. Even if your current app disappears, the content remains usable. Pair text with a predictable folder structure and filenames that include dates or IDs. Periodically open your notes in a different editor to confirm independence. This habit preserves agency and calms experimentation anxiety, because you know that your thinking isn’t trapped behind a proprietary glass wall.
Before committing, perform an export drill: can you get notes, metadata, and links out intact? Explore APIs or community connectors for calendars, tasks, and research libraries. Prefer integrations that pass simple, inspectable payloads. Avoid black‑box sync where conflicts silently swallow changes. If collaboration matters, verify that permissions, version history, and comments survive exports. Treat integration surfaces as part of the selection criteria, not an afterthought, because they determine whether your system grows gracefully.
Decide your threat model: personal notes, sensitive client details, or protected research? Match encryption, device controls, and sharing policies accordingly. Use two locations for backups—automated cloud plus periodic offline snapshots—then rehearse a restore. Check sync reliability across mobile and desktop with airplane‑mode tests. Document your setup so future‑you understands it. Security is not fear; it is freedom to think, write, and collaborate boldly without risking trust or losing irreplaceable work.
