About StonAltar
StonAltar LLC is an independent software company. We build web applications and the platform underneath them, and we sell them directly to the people who use them.
Our main product is Famillium, a private, invite-only home on the web for families and the groups around them. Famillium is sold as monthly and yearly subscriptions at famillium.com.
Behind Famillium is Turnstile (McpAdmin), our identity, access and licensing platform, which handles sign-in, permissions and subscriptions. We also develop Analyst, market-data research software. Neither is for sale yet.
What we stand for
- Privacy first. We don't sell personal information and we don't run ads.
- Plain dealing. Clear prices, easy cancellation, and no surprise charges.
- Built to last. Software that families can rely on for years.
