TheSecureNote Pricing 2026

Open-source end-to-end encrypted notes with encrypted subtree sharing and a permanent free tier

Pricing: Four tiers, monthly or yearly, quoted in USD, EUR or CHF, subscribed inside the app. Every tier including Free carries end-to-end and on-device encryption, encrypted sharing with other users, unlimited note hierarchy, unlimited device sync across Windows, Linux, macOS, Android, iOS and web, offline read/write, automatic conflict resolution and unlimited version history — the paid tiers only raise storage limits. Free: 100 MB total storage, 1 MB max note size, 2,000 notes maximum. Mimiri Tier 1: $1.20/month or $14.40/year, 1 GB storage, 10 MB max note size, 10,000 notes. Mimiri Tier 2: $2.40/month or $28.80/year, 2 GB storage, 10 MB max note size, 20,000 notes. Mimiri Tier 3: $5.50/month or $66.00/year, 5 GB storage, 10 MB max note size, 50,000 notes. The vendor states the free tier is not a trial and will always remain.

Security scanner that ships validated fix PRs, with symbol-level dependency reachability and bring-your-own-LLM detectors

Pricing: Free is $0 forever and covers your whole organisation: up to 5 team members using your own LLM key, up to 100 repositories, 75 validated fix PRs per month, on-demand security analysis, secrets and dependency-CVE detectors, import-level dependency reachability, SAST and AI-app detectors with AI fixes on your own LLM key, and a findings dashboard. Pro is $39 per developer per month billed annually, with a 7-day trial requiring no card, and adds up to 15 team members, unlimited deterministic fix PRs for secrets, dependencies, crypto and CORS, 150 AI-assisted code fixes per month with no LLM key needed, symbol-level dependency reachability via govulncheck, Slack, Jira and Linear integrations posting scan summaries plus a ticket per new high or critical finding, continuous tracking across unlimited repositories and automatic analyze-on-push. Annual billing saves roughly 20%. On paid plans the first seat is free, billing starts once a teammate joins, and pending invites and non-members are not billed.

Compliance firewall that validates, rewrites or blocks every AI output before it reaches anyone

Pricing: Sold through a booked demo; the site publishes no price sheet, so no figures are recorded here rather than guessed.

Automated Linux server and database backup with client-side encryption and immutable WORM storage

Pricing: Priced per server, in EUR, USD or GBP, billed monthly or annually with 20% off annual. Free is €0 forever for a single server with up to 2 services and 10GB of managed storage included, with no credit card. Pro is €5 per server per month with unlimited servers and unlimited services, after a 14-day free trial requiring no credit card and cancellable at any time; storage is either bring-your-own bucket at no charge or managed at €7/TB. The vendor's own calculator shows three servers at €15/month. Enterprise is quoted, adding on-premise or private-cloud deployment, audit logs and compliance exports, SSO via SAML or OIDC, dedicated support with an SLA and priority roadmap input. Crucially, every backup feature — file and database backups, daily or hourly schedules, custom retention, end-to-end encryption and compression, immutable WORM storage, ransomware detection and alerting — is available on both Free and Pro; the only difference between them is how many servers you can connect.

End-to-end encrypted API payloads using post-quantum ML-KEM-768, so logs, CDNs and proxies see only ciphertext after TLS terminates

Pricing: Open Source is $0 forever and includes the complete SDK with no limits: @withnen/client and @withnen/server, ML-KEM-768 key exchange with ChaCha20-Poly1305, mandatory per-request HMAC, encrypted SSE streaming via nenStream, in-memory and Redis session stores, and the public protocol spec and threat model. Cloud is $79/mo and adds a live session and key-rotation dashboard, error-rate and latency monitoring, searchable audit logs, Upstash and edge session backends and email support, with a free trial. Enterprise is custom-priced and adds exportable compliance evidence (ML-KEM-768 per endpoint, timestamped), HSM/KMS integration, SAML/SSO and dedicated support with an SLA. The paid tiers buy visibility and exportable audit evidence rather than the encryption itself, which is free at every tier.
