16.1. Scope. This article applies specifically to SİSTEMDC's S3-compatible object storage service (“Object Storage”). On the matters it governs, this article applies instead of the other articles of this agreement.
16.2. Data location and durability. Data uploaded to Object Storage is stored only in SİSTEMDC's Istanbul data center, within the borders of Türkiye; it is not transferred abroad and no copy is kept abroad. Data is stored in a single location, in a structure that tolerates several simultaneous disk failures, and encrypted at disk level. A geographically separate second copy is not included in the service. Article 4 also applies to this service; the Customer is responsible for keeping a copy of its critical data in a separate location.
16.3. Unit of measurement. Decimal units are used for billing: 1 GB = 1,000,000,000 bytes, 1 TB = 1,000 GB. Usage is measured at byte level. The billed amount is the logical size of the objects uploaded by the Customer, including previous object versions and incomplete multipart uploads. Additional copies and parity space kept by SİSTEMDC for data protection are not billed.
16.4. Price and currency. Object Storage prices are set in US Dollars (USD), excluding VAT; unit prices are stated on the order page. Invoices are issued in Turkish Lira at the exchange rate on the invoice date, with statutory VAT added. Pricing is tiered: the first 5 TB of monthly usage is charged at the first-tier unit price, and the part above 5 TB up to 20 TB at the second-tier unit price. Usage above 20 TB is quoted individually.
16.5. Minimum charge. At least 1 TB is billed each month. If monthly usage is below 1 TB, the 1 TB charge still applies.
16.6. Calculation of monthly usage. Monthly usage is the average, over the month, of the Customer's storage measured each day. Usage above 1 TB is calculated per GB, pro rata. Charges for deleted data end on the day it is deleted; no separate fee is charged for deleted data.
16.7. Minimum commitment period (3 months). The minimum commitment period of the Object Storage service is 3 months from the date the service is activated. During this period at least the minimum charge under Article 16.5 is billed each month. If the Customer ends the service before the 3 months have passed, the minimum charge for the remaining months of the commitment period is added to the final invoice; this amount is not claimed where the service ends for reasons attributable to SİSTEMDC under Article 9.5. After the 3 months, the service continues monthly and the Customer may end it at any time.
16.8. Payment. The minimum charge (1 TB) is paid monthly in advance. Usage above the minimum is calculated at the end of the month concerned and added to the next invoice; Article 8.1 does not apply to this part. The Customer can follow a detailed breakdown of its usage in the customer panel. These charges arise from the usage-based pricing accepted by the Customer when ordering and are deemed charges approved in advance within the meaning of Article 7.6.
16.9. Requests and data download. API requests (upload, list, read, delete) and data download are not charged separately. If the monthly download volume exceeds the average storage amount for that month, SİSTEMDC warns the Customer and may limit the connection speed without charging any fee for the excess.
16.10. Quota. SİSTEMDC may set a storage quota per account to protect the infrastructure. The Customer may request a quota increase free of charge; the space used is billed at the prices under Article 16.4.
16.11. Object Lock (immutable storage). The Customer may use Object Lock on its own buckets and is responsible for setting the retention period according to its own needs. Objects locked in “Compliance” mode cannot be deleted or modified by either the Customer or SİSTEMDC until the retention period ends. Charges for these objects accrue until the end of the retention period even if the service is suspended or the agreement is terminated or expires. SİSTEMDC reserves the right to block access to these objects where required by law.
16.12. Personal data. With respect to the data uploaded by the Customer to Object Storage, the Customer is the data controller and SİSTEMDC is the data processor. SİSTEMDC stores this data only to provide the service; except where required by law, it does not access or examine its content or transfer it to third parties. At the Customer's request, the parties sign a separate Data Processing Agreement. Access logs of the service (time, IP address, operation performed) are retained for security purposes and legal obligations for the period set by the applicable legislation.
16.13. Suspension and termination. If payment is not made, Article 8.5 applies; during suspension the data is preserved but access is closed. When the service is closed or the agreement ends, all data except objects locked with Object Lock is permanently deleted and cannot be recovered; Article 9.8 is reserved. The Customer is responsible for moving its data before the service ends. The final invoice includes usage above the minimum for the last month and, where applicable, the remaining commitment amount under Article 16.7.
16.14. Refunds. Usage-based charges and the commitment amount under Article 16.7 are not refunded. The 15-day refund right under Article 9.3 applies only to the first month's minimum charge paid in advance and only if no data has been uploaded to the service; in that case the remaining commitment amount is not claimed either.
