Nolio

Nolio is a free, open-source notes app that keeps an encrypted vault on your devices rather than in a hosted account. It is best for privacy-conscious users who still want structured, multimedia notes on desktop, web, and Android. The trade-off is absolute responsibility for the master password and backups.

Overview

Nolio takes a local-first approach: notes remain on the device, with no cloud service, third-party server, or telemetry in the product’s design. Desktop data is held in encrypted SQLite, while the web version uses IndexedDB. That makes it suitable for journals, research, personal records, and work material that you do not want routed through a vendor’s infrastructure.

The same architecture removes account-style recovery. There is intentionally no password reset, and notes cannot be recovered without the master password. You can export an encrypted vault backup to a location you select; importing verifies the backup password before changing the vault. Users who want control over storage will appreciate that arrangement, while anyone who regularly forgets credentials should look elsewhere.

Key features

Rich editing and Markdown

The Plate-based editor supports headings, lists, task lists, quotations, code blocks, callouts, tables, images, and links. Pasted Markdown is converted into rich blocks, and slash commands let keyboard users insert blocks without leaving the editor. It is a credible choice for project documentation and knowledge notes, not merely short text memos.

Organization and quick access

Notes can sit in nested pages with unlimited subpages. Favorites, Recent, All Notes, Trash, and a command palette provide several ways to reach material as the vault grows. The structure favors users who build topic hierarchies; it may be more machinery than someone seeking a single flat inbox.

Security controls

Each note uses AES-256-GCM encryption. Keys are derived with Argon2id, or with a 600,000-iteration PBKDF2 fallback. The vault can auto-lock after a configurable idle period, and Cmd/Ctrl + Shift + L locks it immediately. These controls reduce exposure on shared or unattended machines, but they do not compensate for a lost master password.

Desktop widgets

Desktop editions can open resizable, frameless sticky-note windows and pin them above other windows. That is useful for temporary checklists or reference snippets while working in another application, especially for users who prefer an always-visible desktop surface.

Pricing

There is no free trial because the product is free, and no paid tier or renewal term is given. The absence of a stated quota is attractive for personal vaults, but readers who require a contractual storage allowance or hosted synchronization should consider a service with explicit capacity terms.

Platforms

Nolio runs in a browser and on Windows, macOS, Linux, and Android. Desktop downloads include Windows EXE and MSI installers, macOS DMGs for Apple Silicon and Intel, and Linux AppImage, DEB, and RPM packages. The broad desktop coverage suits mixed-device households, while Android support extends the vault beyond a computer. No iOS edition is included. The project describes local features but does not list third-party integrations or an API.

Who it's for

Choose Nolio if keeping data off vendor servers matters, you want a capable block editor, and you are prepared to maintain encrypted backups. It is particularly well matched to technically confident users who value open-source software and cross-platform access.

It is a weaker fit for teams needing collaboration, integrations, or centralized account recovery. The local vault model also puts migration and backup responsibility on the individual rather than a service operator.

Pros and cons

• Pros: per-note AES-256-GCM encryption with Argon2id or a strong PBKDF2 fallback; no cloud, telemetry, or third-party storage; rich blocks, Markdown conversion, and slash commands; unlimited nested pages; configurable auto-lock and encrypted exports; free and open source across five platform categories.
• Cons: no password reset, so a forgotten master password can permanently block access; no iOS app; no stated usage quota or service-level storage terms; no listed integrations or API; backups and recovery are your responsibility.

Alternatives

For a broader directory of privacy-focused choices, see Secure Notes Apps.

• Notesnook is the better pick if you want freemium service terms, a free trial, iOS support, and a free tier with stated storage limits.
• Cryptee suits readers who want open-source cryptography, iOS support, and a free 100 MB tier.
• PrivacyNotes is worth choosing for an AGPL-published web, desktop, and mobile codebase with iOS coverage.
• Standard Notes is an alternative for end-to-end encryption, unlimited device sync, plain-text notes, and offline access.
• Dash fits users seeking an open-source, offline-capable PWA or iPhone app without an account.
• Notyra is another free, open-source option that begins without an account.
• QOwnNotes is an alternative free application with a wider set of listed deployment options.
• Turtl is the better direction when collaborators and explicit storage tiers matter, including a Premium plan at $3 a month.

Verdict

Nolio is a strong choice for an individual who wants rich notes, broad platform coverage, and encryption that stays under personal control at no cost. Its decisive weakness is the lack of password recovery, compounded by the need to manage backups yourself. Pick it for privacy and ownership; look elsewhere if dependable account recovery, iOS support, collaboration, or hosted integrations are priorities.
