About this site

asymptotically.me is a personal hobby project, not a company. I built it for fun and to share tools I find useful. Hosting and infrastructure have running costs, which is why some features require payment — but I have no commercial interest in your data. I will never sell it, analyse it for marketing purposes, or share it with anyone.

What I collect and why

Connecting your Notion account is required to use the site, including the free template gallery. This is the only account system in place — your Notion identity is used solely to recognise you as a returning user and to track any premium access you have purchased. When you connect Notion, I store:

• Your Notion OAuth access token
• Your Notion workspace name
• Your Notion account email address

Nothing beyond these three fields is collected from your Notion account. The OAuth token obtained during sign-in has the same technical capabilities regardless of what you use — however, the application will only read from or write to your Notion databases if you have purchased a database-backed widget (such as the Reading List). In that case, your token is used solely to operate the specific database you connect. No other databases or pages are accessed.

Storage

Your data is stored in a private Supabase database, accessible only to me as the site owner. A user_id cookie in your browser links your session to your stored record.

Cookies

I use a single user_id cookie to identify your session. It is HttpOnly, uses a lax same-site policy, and lasts one year. No tracking, analytics, or advertising cookies are used.

Your rights

You can revoke Notion access at any time from your Notion connected integrations settings.
