Subject to legal conditions, you may request access to your data, correction, erasure, restriction of processing, data portability, and object to processing based on legitimate interests. If you are in Türkiye, you also have the rights listed in KVKK Article 11. Send requests to hello@periscube.com. We respond within one month under UK/EU GDPR and within 30 days under KVKK.

8. Complaints

If you are unhappy with how we handle your data, please contact us first. You also have the right to complain to the UK Information Commissioner's Office (ico.org.uk), the Turkish Personal Data Protection Authority, KVKK (kvkk.gov.tr), or the supervisory authority in your EU country of residence.

9. Security

We protect personal data with access controls, encryption in transit, multi-factor authentication on business systems, and least-privilege access. No method of transmission over the internet is completely secure, so please do not send sensitive personal data through the contact form.
