Refund & Cancellation Policy
SiriPlan subscriptions and add-ons · Effective: 10 October 2026
This is a convenience translation; the Turkish text is authoritative.
This policy forms an integral part of the Distance Sales Agreement. A consumer's statutory rights are reserved and this policy does not limit them. The Turkish text is authoritative.
1. Cancelling Your Subscription
You can cancel at any time in Settings → Subscription or by emailing info@bysirius.com. Cancellation stops the next automatic renewal; you keep using the service until the end of the period you paid for. After that, your account moves to a free/restricted state; your right to export data is set out in the Terms of Use.
For Business Buyers, cancellation only takes effect going forward; the fee for a period that has started is not refunded.
2. When Are Refunds Given?
No pro-rata refund is made for a subscription period that has started. The following are reserved and will be assessed on request:
a) Duplicate or erroneous charges (several charges for the same period, wrong amount, etc.): the excess is refunded in full.
b) A Seller-side technical failure that makes the service effectively unusable and is not fixed within a reasonable time: pro-rata refund or credit for the affected time.
c) The consumer's statutory withdrawal and refund rights (Section 3).
d) Other cases required by law.
To request a refund, email info@bysirius.com with your account email, charge date and amount. Requests are answered within 10 business days at the latest.
3. Consumer Withdrawal and Immediate Start of the Service
The service is performed instantly in electronic form. A consumer who gives the consent at checkout (“I want the service to start immediately and I understand I lose the right of withdrawal once performance begins”) cannot withdraw after performance has begun.
If a competent authority holds this consent not valid in the case, or the consumer withdraws before the service starts, the amount for the unused part is refunded to the payment method used within 14 days at the latest after the notice reaches the Seller; the part actually used until the withdrawal date (pro-rata daily) is deducted.
Refunds are made to the same card through Stripe; how fast your bank posts it depends on the bank. The Seller does not charge a refund fee, but fees applied by your bank for foreign transactions/exchange rates are not reimbursed by the Seller.
4. Plan Changes (Upgrade / Downgrade)
Upgrade: the unused part of the current period is credited, the difference is charged immediately and a new period starts at the upgrade.
Downgrade: the current period is kept; the unused difference is applied as account credit against future payments. A downgrade does not result in a cash refund.
The Mini plan is limited to 1 active staff member; extra staff must be deactivated before switching to Mini.
5. Add-ons (e.g. SMS Credits)
One-off digital add-ons such as SMS credits are assigned to the account at purchase and are electronic content performed instantly. Used credits are not refunded. Subject to the consumer's consent and the law, statutory withdrawal/refund rights for entirely unused credits are reserved. For Business Buyers, refunds for unused credits are at the Seller's discretion.
6. Failed Payments and Declined Cards
If a renewal payment cannot be collected, the Seller may retry a reasonable number of times and will notify the Buyer. If payment is not completed, the subscription ends and the account moves to a free/restricted state.
