+# Sentinel Protocol FAQ (Frequently Asked Questions)
+
+---
+
+### Q1: If the company behind Sentinel Protocol shuts down, can I still retrieve my data and heritage?
+**A: Yes.** Sentinel Protocol is designed with "non-dependency" as a core principle:
+* **Data Persistence**: Your core data is stored on decentralized networks like Arweave/Filecoin. Its physical existence does not depend on our central servers.
+* **Self-Rescue Kit**: The decryption tool code is entirely open-source. Even if the company ceases to exist, as long as you hold your full mnemonics or shards (S0/S1/S2), you can independently retrieve and decrypt your data using open-source tools.
+* **DAO Takeover**: Smart contracts automatically monitor company activity. If a "failure state" is triggered, control of the protocol is automatically transferred to a Decentralized Autonomous Organization (DAO).

+
+### Q2: How do you prevent an heir (holding S2) from colluding with the platform (holding S1) to steal my assets?
+**A: Technical isolation makes collusion impossible.**
+Before your status is determined as "Released," the distributed nodes storing S1 shards are in a **logically locked state**. No node will provide its shard unless it detects a "Proof of Status" on the blockchain (a legitimate release signal signed by the smart contract). Even if an heir has the S2 credential, they cannot reverse-engineer the ciphertext without the system-generated release command.

+
+### Q3: What if I am just in a temporary coma or working in an area with no signal (e.g., on the high seas)? Will the system misjudge me as deceased?
+**A: No.** We have designed the **Double-Lock Mechanism**.
+* **Freezing Period**: You can preset a freezing period of 180-365 days. When a heartbeat signal is interrupted, the system first enters a "Pending" state.
+* **One-Click Abortion**: During this long freezing period, the release process can be immediately terminated and reset as soon as you come back online or your emergency contact intervenes.
+* **Sleep Mode**: If you plan an extended offline expedition, you can manually activate "Sleep Mode" to pause monitoring.
+
+---
+
+### Q4: My financial situation is unstable recently; can I temporarily stop my subscription?
+**A: Yes.** You can activate **"Sleep Mode"** at any time.
+* **Physical Retention**: During the pause, active services like AI monitoring will stop, but your data will remain physically sealed in the storage network and will not be deleted.
+* **Instant Wake-up**: You only need to pay a small storage maintenance fee in the future to reactivate the "Sentinel" to its full active state.
+* **Extreme Extraction**: Even during a pause, if an extreme event occurs, heirs can still settle outstanding fees and trigger the extraction process according to the protocol.
+

+
+### Q5: Does the AI see my privacy (e.g., passwords, will content) when sorting data?
+**A: Absolutely not.**
+* **Local Encryption**: Data is heavily encrypted before it even leaves your device.
+* **Shadow Proxy Technology**: The AI only processes metadata within a **TEE (Trusted Execution Environment)**. The AI is responsible for indexing and suggesting archives but does not have the key authority to decrypt the ciphertext, meaning it cannot read the actual content of your files.
+

+
+### Q6: is the Sentinel Protocol legally valid? Can heirs use the exported keys for legal title confirmation?
+**A: Yes.** * **Legal Pre-declaration**: When you set up an S2 recipient, the system generates a "Notice of Authorization" based on a digital signature, clarifying that this act is a legal "Gift/Inheritance" authorization.
+* **Notary Integration**: For L2 users, we provide full-process legal notarization support.
+* **Multidimensional Evidence**: The extraction process is recorded on the blockchain, ensuring the authenticity of the inheritance and avoiding potential legal disputes.
+
+---
+
+### Q7: Why is the duration for L0 users only 10 years?
+**A: This is to ensure the robustness of the financial model.**
+10 years is a financial equilibrium point designed to cover the initial storage costs of decentralized networks and the hedging fees of the Protocol Reserve Pool. After expiration, data enters an "Extended Retention State," where heirs only need to pay a very small storage gap to complete the extraction. This design ensures the protocol remains resilient over decades.

+
+### Q8: If I lose all my mnemonics, can you help me recover them?
+**A: Sorry, we cannot.**
+Sentinel Protocol adheres to a **non-custodial** principle. If you lose all your shards and have no backup of your original mnemonics, the platform does not hold your master key, and no one can force open your vault. This is the ultimate guarantee of your sovereignty and the final boundary of security.
