If an account is inactive for 90 days, the points will expire. Inactive status means there have been no finished receipts within that time period. Fetch will notify users via the email address on the account before their points are expired.
Please note, even though you may receive points for SingleCare or Referrals, if receipts aren't scanned, those points may be awarded, then subsequently removed. Please keep scanning your receipts so points do not expire.
