Learn Turkish: Kişisel verilerini şifrelemelisin, aksi takdirde çalınır. - You must encrypt your personal data, otherwise it will be stolen.

It literally translates to "in the opposite event." Aksi means "opposite" or "contrary", and takdirde means "in the case/event of". It acts as a bridge, introducing the negative consequence that will happen if the action in the first clause (şifrelemelisin) isn't completed.

Can you break down the suffixes on verilerini?

It starts with the root noun veri (data). Then we add -ler (plural), -in (your), and finally the accusative case suffix -i. The accusative is required here because "your data" is the specific direct object of the verb "you must encrypt".

How do we get the verb "to encrypt" from the word şifrelemelisin?

The base is the noun şifre (code or cipher). The suffix -le is a very common verb-maker, turning it into şifrele- (to encode/encrypt). To finish the word, we add the necessity suffix -meli (must) and the personal ending -sin (you).

Why does çalınır use the aorist (broad time) tense instead of the future tense (çalınacak)?

While çalınacak (will be stolen) is grammatically fine, the aorist çalınır is extremely common for expressing logical consequences or predictions. In "otherwise" scenarios, the aorist gives a strong sense of "this is what naturally happens" rather than describing a scheduled future event.
