Support and participation terms · Version 1.0 · September 2026
Know what your support means.
These terms cover recurring ACAIF support seats and the wider Pledge 1% for Human Progress participation framework.
Short summary
When you take a support seat, you authorise recurring billing through Stripe at the seat quantity and billing cadence shown before checkout. Annual support is billed once a year and monthly support once a month. You may end future recurring billing. Support already processed is handled under ACAIF's applicable refund and financial-record requirements. Participation does not mean ACAIF endorses, accredits or formally partners with you.
1. What a support seat is
A support seat is a recurring contribution to ACAIF's public-interest work. The standard price is US$9.99 per seat per month or US$119.88 per seat per year. The number of seats is a way to choose the level of support. It is not an ownership interest, membership share, investment product, entitlement to services or measure of influence over ACAIF.
2. Recurring billing
Checkout is completed through Stripe. By completing checkout, you authorise Stripe to charge the payment method you provide according to the seat quantity and cadence displayed at checkout until the subscription ends. ACAIF's server determines the price and quantity sent to Stripe; card details remain within Stripe's payment environment.
3. Annual and monthly support
Annual support is the preferred option because it gives ACAIF a steadier base for planning. An annual subscription renews annually and a monthly subscription renews monthly unless it is ended before the next billing cycle. Stripe's checkout and billing records provide the final payment amount and status for each transaction.
4. Changes, cancellation and failed payments
You may ask ACAIF to change or end future recurring support, and ACAIF may provide a Stripe billing portal for self-service management. Ending a subscription stops future renewal according to the effective cancellation date shown by Stripe. If a payment fails, Stripe or ACAIF may send a transactional notice so you can update the payment method. ACAIF may pause or end a subscription that remains unpaid.
5. Refunds
If you believe a contribution was made in error, duplicated or requires correction, contact ACAIF promptly with the support reference or Stripe receipt. Refund requests are reviewed against the payment record, any funds already committed or disbursed, and applicable legal or financial obligations. Nothing in these terms limits rights that cannot lawfully be excluded.
6. Individual and group support
Individuals may support in their own name. A group or organisation may support under a shared name. The person submitting group support confirms that they are authorised to use the group or organisation name for that contribution. A support record does not by itself establish an ACAIF partnership, sponsorship, endorsement or accreditation.
7. Communications
Payment confirmations, receipts, renewal or payment-failure notices and other messages needed to administer the subscription are transactional. Research, impact and supporter updates require the separate communication choice shown on the form and can be turned off without ending the support subscription.
8. Existing public pledges
Earlier self-declared Pledge 1% for Human Progress records may remain in ACAIF's public or private pledge system. Those records are declarations of commitment rather than automatically recurring paid support. Public pledge profiles remain subject to moderation, identity safeguards and withdrawal. Use of any pledge mark must not imply ACAIF endorsement, certification or partnership.
9. Privacy and records
ACAIF records the information reasonably needed to administer support, consent, communications, reconciliation and financial controls. Full payment card details are handled by Stripe rather than stored by the ACAIF website. See the Privacy and Data Use notice for more detail.
10. Misuse and refusal
ACAIF may refuse, suspend or remove participation associated with fraud, impersonation, abuse, malicious activity or materially misleading claims about a relationship with ACAIF. Financial records may still be retained where required for reconciliation, fraud prevention, audit or law.
11. Updates to these terms
ACAIF may update these terms as the support model and movement evolve. The system records the version and acceptance time for new support. Material changes that affect an active recurring subscription should be communicated where appropriate.
