Proton Mail is the default for people who want email that providers can't read: end-to-end encryption, Swiss jurisdiction, and a free tier to start. Paid plans fold in VPN, Drive, and Calendar for a genuinely private ecosystem. The trade-offs are the usual privacy tax — some features need Proton's own apps, and search isn't as slick as the big providers.
Sticky Password covers the essentials and adds two things enthusiasts love: local Wi-Fi-only sync that keeps your vault off the cloud entirely, and a one-time lifetime licence. It's a smaller player with a dated interface, but for its niche — local control or a buy-once model — it delivers, and a share of sales funds manatee conservation.
In our reviews Proton Mail scores 4.7/5 and Sticky Password scores 4.2/5, but the better tool depends on your needs: Proton Mail suits privacy-conscious people who want encrypted email and a private ecosystem, while Sticky Password suits users who want local sync or a one-time lifetime purchase.
Proton Mail uses a freemium model and Sticky Password a freemium model. Both offer paid plans, so compare the entry tiers above for your usage. Always confirm current pricing on each vendor's site.
Choose Proton Mail if privacy-conscious people who want encrypted email and a private ecosystem is your priority and end-to-end encryption by default matters most. Choose Sticky Password if you are users who want local sync or a one-time lifetime purchase and you value local wi-fi sync keeps data off the cloud.
