المزامنة محتاجة صلاحية الوصول.

Because المزامنة is a grammatically feminine noun. You can see that from the ending ـة.

In Egyptian Arabic, محتاج / محتاجة agrees with the noun it describes:

• محتاج = masculine
• محتاجة = feminine

So:

• البرنامج محتاج... = The program needs...
• المزامنة محتاجة... = The sync/synchronization needs...

Literally, محتاجة means needing or in need of.

In Egyptian Arabic, this is a very common way to express need:

• أنا محتاج مساعدة = I need help
• هي محتاجة وقت = She needs time

So in this sentence, المزامنة محتاجة صلاحية الوصول is very natural in Egyptian-style usage and means the synchronization needs access permission.

There could be. Both are possible, but they belong to slightly different styles.

• المزامنة محتاجة صلاحية الوصول sounds more Egyptian/colloquial-neutral.
• المزامنة تحتاج إلى صلاحية الوصول sounds more formal or more like Modern Standard Arabic.

So the given sentence uses a very common Egyptian pattern: noun + محتاج/محتاجة + thing needed.

Because in Egyptian Arabic, محتاج / محتاجة usually takes its complement directly, without a preposition.

So you say:

• أنا محتاج فلوس = I need money
• التطبيق محتاج تحديث = The app needs an update

In more formal Arabic, you often get:

• يحتاج إلى... = needs... / needs to...

But in Egyptian, dropping that preposition is normal with محتاج.

It is a noun phrase meaning access permission or permission to access.

It is built as an iḍāfa construction, which is basically a noun + noun relationship:

• صلاحية = permission / authorization / privilege
• الوصول = access / reaching

Together:

• صلاحية الوصول = access permission

In tech language, this is a common formal phrase for app permissions.

Because this is how iḍāfa works.

In an iḍāfa:

• the first noun usually does not take الـ
• the second noun can be definite with الـ
• the whole phrase becomes definite because of the second noun

So:

• صلاحية الوصول = the permission of access / access permission
• not الصلاحية الوصول in this structure

This is a very common pattern in Arabic.

It is a bit mixed, which is very normal in technology, UI text, and modern spoken Arabic.

• محتاجة feels Egyptian/colloquial-friendly
• المزامنة and صلاحية الوصول are more formal/technical words

That mix is extremely common in app messages, settings, and notifications. A speaker may use colloquial grammar with formal tech vocabulary.

Yes. That version is correct and more formal.

Compare the two:

• المزامنة محتاجة صلاحية الوصول = more Egyptian-style, natural in everyday/UI language
• المزامنة تحتاج إلى صلاحية الوصول = more formal/standard

Both mean essentially the same thing.

A careful Egyptian-style pronunciation could be:

el-mozāmana meḥtāga salāḥeyyet el-woṣūl

A few notes:

• الـ is usually pronounced el-
• ح in محتاجة is a strong ḥ sound from the throat
• ص in الوصول is an emphatic ṣ

Because this is a technical word, pronunciation may vary a little from speaker to speaker, especially with المزامنة.

In a tech sentence like this, المزامنة can refer broadly to sync, synchronization, or the syncing process/feature.

So depending on context, English might render it as:

• Sync needs access permission
• Synchronization needs access permission
• The sync feature needs access permission

Arabic often leaves that slightly broad, and the app context makes it clear.

Yes, but the sentence is quite straightforward.

This is basically:

• المزامنة = subject/topic
• محتاجة صلاحية الوصول = predicate/comment about it

So the structure is: [thing] + [needs + object]

That makes it sound natural and clear:

• المزامنة محتاجة صلاحية الوصول

You could rearrange things in other contexts, but this is the normal, simple order for a message like this.
