Obsidian Settings for a Faster, Safer, Private Vault
To make Obsidian faster, safer, and more private, you need to adjust a handful of core settings: disable expensive features like automatic link updates and spellcheck, turn on encryption for your vault, and configure the app to avoid sending data to third-party servers. This article walks through the specific settings to change, why they matter, and what trade-offs to expect.
Background: Why Obsidian’s Defaults Aren’t Optimal
Obsidian is a local-first note-taking app that stores everything as plain Markdown files on your device. That’s great for privacy and longevity, but the default settings are tuned for convenience, not for maximum speed or security. For example, Obsidian automatically indexes your entire vault, updates links when you rename files, and syncs with community plugins—all of which can slow things down on large vaults. Similarly, while your notes stay local, the app itself can make network requests for updates, telemetry, and community plugin listings. Understanding what each setting does helps you make informed choices.
Speed: Key Settings to Change
If your vault feels sluggish, start with these settings under Settings → Files & Links and Settings → Editor:
- Disable “Automatically update internal links� — This prevents Obsidian from scanning all files when you rename a note, which can be a major slowdown on large vaults.
- Turn off “Detect all file extensions� — Unless you need it, restricting to Markdown files reduces indexing load.
- Disable “Spellcheck� — Real-time spellcheck adds overhead, especially on long documents.
- Set “Performance mode� to “Minimum� (if available) — This reduces animations and background processing.
- Limit “File recovery� history — Under Settings → File Recovery, reduce the number of snapshots kept to avoid excessive disk writes.
- Disable unused community plugins — Each plugin runs in the background; fewer plugins means faster startup and smoother typing.
For very large vaults (10,000+ notes), consider splitting into multiple vaults or using folders with fewer files per folder. Also, keep your vault on an SSD rather than a spinning hard drive.
Safety: Protecting Your Data
Safety here means both preventing data loss and avoiding accidental changes. Key settings:
- Enable “File recovery� — Under Settings → File Recovery, turn it on and set a reasonable snapshot interval (e.g., every 5 minutes). This keeps versions of your notes so you can undo mistakes.
- Turn on “Trash� — Under Settings → Files & Links, set “Deleted files� to “Move to system trash� instead of permanent deletion. This gives you a safety net.
- Disable “Read all filesâ€� — If you don’t need Obsidian to index non-Markdown files, turn this off to reduce the chance of accidental edits.
- Use “Strict line breaks� — This prevents formatting surprises when sharing notes.
Beyond settings, always back up your vault. Since Obsidian stores plain files, you can use any backup service (like a cloud folder or an external drive). Consider versioning with a tool like Git if you’re comfortable with command line.
Privacy: Minimizing Data Leakage
Obsidian is local-first, but it still makes network requests. To tighten privacy:
- Turn off “Telemetry� — Under Settings → About, uncheck “Send anonymous usage data.�
- Disable “Update checker� — Under Settings → General, turn off “Automatically check for updates.� You can manually update when you choose.
- Use a local-only vault — Avoid syncing to Obsidian Sync or third-party cloud if you want zero cloud exposure. If you need sync, use an end-to-end encrypted service.
- Block network access for Obsidian — On Windows, you can use firewall rules; on macOS, use Little Snitch or similar. This prevents any background connections.
- Be careful with community plugins — Only install from trusted sources, and review permissions. Some plugins may send data to external servers.
Remember, Obsidian’s core is offline, but plugins can introduce network calls. The safest is to run Obsidian with no plugins and no sync.
How to Choose: Balancing Speed, Safety, and Privacy
There’s no one-size-fits-all. A student with 500 notes may not need to disable link updates, while a researcher with 50,000 notes will. Similarly, a journalist handling sensitive sources may prioritize privacy over convenience. Start by assessing your vault size and threat model. If you’re unsure, start with the speed and safety settings above; they rarely hurt. For privacy, the most impactful change is disabling telemetry and update checks, which you can do without losing functionality.
Common Problems and Misconceptions
One common misconception is that Obsidian’s “Safe modeâ€� (disabling community plugins) makes the app more secure. It does reduce third-party code, but it doesn’t affect Obsidian’s own network behavior. Another is that turning off link updates will break your notes—actually, it only stops automatic renaming; you can still manually update links. People also worry that disabling spellcheck makes them less productive; but you can always run a manual spellcheck via a plugin or external tool.
If you notice Obsidian is slow even after changes, check if you have a huge number of files in a single folder, or if you have a plugin that’s misbehaving. Try disabling all plugins to see if speed improves.
Comparisons: Obsidian vs. Other Tools
Compared to cloud-based note apps like Notion or Evernote, Obsidian is already more private because your data stays local. However, those apps offer built-in sync and collaboration, which Obsidian requires plugins or paid sync for. For speed, Obsidian can be faster than web-based apps, but slower than minimal text editors like Vim or Typora. If you need maximum privacy, you might also consider plain text files with a simple editor, but you lose Obsidian’s linking and graph features.
Costs and Alternatives
Obsidian is free for personal use, and you can use it indefinitely without paying. The paid “Sync� service is optional and end-to-end encrypted. Alternatives like Logseq, Joplin, or Standard Notes offer similar local-first features with different trade-offs. Joplin has built-in encryption, while Logseq has a different workflow. Standard Notes focuses on privacy with end-to-end encryption by default. Each has its own settings for speed and privacy, so the same principles apply: disable telemetry, limit indexing, and back up.
Frequently Asked Questions
Does disabling telemetry actually stop all data collection?
Disabling telemetry stops Obsidian’s anonymous usage data, but the app may still check for updates or access community plugin repositories unless you also disable those. For absolute privacy, block network access at the firewall level.
Will turning off automatic link updates break my notes?
No. It only stops Obsidian from automatically updating links when you rename a file. You can still update links manually or use a plugin to do it on demand. Your existing links remain intact.
Can I use Obsidian without any internet connection?
Yes, Obsidian works fully offline. You can create, edit, and search notes without an internet connection. Just disable update checks and telemetry to avoid any connection attempts.
What’s the best way to back up a vault?
Because Obsidian stores plain Markdown files, you can simply copy the vault folder to an external drive or cloud storage. For versioning, use a tool like Git or a file sync service with version history.
Is Obsidian Sync worth it for privacy?
Obsidian Sync is end-to-end encrypted, meaning only you can read your notes. It’s convenient and private, but you can achieve similar privacy with a third-party encrypted sync tool like Cryptomator or a self-hosted solution.
Why is my vault slow even after changing settings?
If the vault is still slow, check for large attachments, a huge number of files in one folder, or a plugin that’s consuming resources. Try creating a new empty vault and see if the issue persists; if not, the problem is likely in your vault’s content or plugins.
