Yes. Every tier, including Stone, sees the full provider pool: free resources, paid programs, and direct booking links. The difference between tiers is how many children, subjects, and plan updates each supports, not whether the recommendations themselves are useful.
Yes. You can upgrade, downgrade, or cancel from your account at any time. Changes take effect at the start of your next billing period.
Everything in the Cairn or Trail plan: every subject, all available providers, and the weekly plan refresh. We'll remind you two days before the trial ends.
No. You pay the provider's normal price directly. Some providers pay Cairn a referral fee when you book through us, which we disclose on each link. That fee doesn't change what you pay, and it doesn't decide what we recommend.
Children's information stays inside your account. We don't sell it, share it with advertisers, or use it to train third-party AI models.
If you cancel within the first 30 days of a paid plan, we'll refund your most recent charge. No questions, no forms.
Yes, we work with international schools and family-support nonprofits on bulk seats. Email partners@cairnplan.com and we'll send terms.
