Share Calvin. Earn Plus.

Every Calvin user gets a unique referral link. Send it to a friend. When they sign up and start using him, you get Plus tier on the house. No coupon codes, no tracking pixels, no fine print.

1
Your friend signs up and sends their first message
You get 7 days of Plus. Immediately, on their first real use.
2
Your friend is still active 30 days in
You get another 14 days. Because Calvin stuck for them, not because they opened the page once.
3
Your friend upgrades to paid
You get 30 more days. Totals stack. Ten referrals can keep you on Plus for a long time.

Where do I get my link?

Sign in to your dashboard. The "Refer friends" card shows your code and a copy button. Paste the link into a text, an email, a Slack, wherever your friend is. Works on the website, works in the WhatsApp chat they open with Calvin.

What counts as a referral?

A friend who clicks your link, books a demo, completes onboarding, and sends at least one real message to Calvin. We do not count empty signups.

Do rewards expire?

The Plus tier bump stacks. Each earned day adds to your current expiry. Once the bump runs out you drop back to your base plan, unless you have paid Plus directly.

Can I refer as many friends as I want?

Yes. No cap. Each qualifying signup, retention milestone, and paid conversion stacks. Operator tier is the one thing referrals cannot unlock. Operator stays paid-only.

What if my friend already had a trial?

Calvin's trial-abuse guard blocks re-registering the same phone, so only genuinely new users qualify. No partial credit.
