Автопродление указано в договоре хранения.

Автопродление is a compound noun meaning automatic renewal or auto-renewal.

It is built from:

• авто- = auto-, automatic
• продление = extension, renewal

So in contracts and service language, автопродление usually means that something is renewed automatically unless someone cancels it.

Указано is the short passive participle of указать (to indicate, specify, state).

Here it means something like:

• is specified
• is stated
• is indicated

The ending -о is used because it agrees with автопродление, which is:

• neuter
• singular

Compare:

• пункт указан — the clause is stated (masculine)
• цель указана — the purpose is stated (feminine)
• автопродление указано — the auto-renewal is stated (neuter)

Because it is the grammatical subject of the sentence.

The sentence structure is basically:

• Автопродление = the subject
• указано = the predicate (is stated / is specified)

So автопродление stays in the nominative.

A good literal breakdown is:

• Автопродление — auto-renewal
• указано — is specified
• в договоре хранения — in the storage contract

Because after в meaning in, Russian normally uses the prepositional case for location.

So:

• договор = contract, agreement
• в договоре = in the contract

This sentence is talking about where the information is written, so it is a location idea, not motion.

Compare:

• в договоре = in the contract
• в договор = into the contract

Хранения is the genitive singular of хранение (storage, keeping, safekeeping).

Russian often uses a noun + noun in the genitive structure where English would often use an adjective or a compound noun.

So:

• договор = contract
• хранение = storage
• договор хранения = storage contract / contract for storage

Literally, it is something like contract of storage.

Yes. Both are possible depending on context.

• storage contract is a very direct translation
• storage agreement may sound slightly more natural in some legal/business contexts

Russian договор can often be translated as either contract or agreement, depending on how formal or legal the situation is.

Russian normally does not use a present-tense form of to be the way English does.

But in this sentence, the main predicate is not just an omitted is. The key word is указано, which already carries the idea of is stated / is specified.

So the sentence is not:

• Автопродление есть...

Instead, it is:

• Автопродление указано... = Auto-renewal is specified...

Yes. Russian word order is flexible.

For example, these are also possible:

• В договоре хранения указано автопродление.
• Указано автопродление в договоре хранения.

But the original order:

• Автопродление указано в договоре хранения.

is natural if you want to put the focus first on автопродление.

Very roughly:

• starting with автопродление emphasizes what is stated
• starting with в договоре хранения emphasizes where it is stated

Good question. Both forms come from the verb указывать / указать, but they work differently.

• указано = is stated / is specified as a fact or result
• указывается = is being stated / is stated in a more process-like or regular-description sense

In legal or document language, указано is very common when you mean that something is written there as a completed fact.

So:

• Автопродление указано в договоре хранения = Auto-renewal is stated in the storage contract.

This sounds more like the contract contains that information.

Yes, it sounds fairly formal and document-like.

Words and structures such as:

• автопродление
• указано
• в договоре хранения

are typical of administrative, legal, or customer-service language.

In more everyday speech, a person might say something less formal, for example:

• В договоре написано, что есть автопродление.
  • It says in the contract that there is auto-renewal.

That version sounds more conversational.

A natural translation would be:

• The auto-renewal is specified in the storage contract.
• Auto-renewal is stated in the storage contract.

Depending on context, you might also say:

• The storage contract mentions automatic renewal.
• Automatic renewal is specified in the contract.

If you already know from context which contract is meant, English often adds the, even though Russian has no articles.
