How Replio Cares for Your Security? A Comprehensive Guide

The year 2025 is the time when Artificial Intelligence ceased to be a novelty and became a standard in e-commerce. However, along with the growing popularity of AI tools, seller concerns are also rising. We hear about data leaks, "hallucinations" of language models, and unauthorized access. It is natural that as an entrepreneur for whom an Allegro account is a source of livelihood, you approach innovations with reserve.

"Will AI ruin my reputation with one stupid message?", "By providing API keys, am I giving away access to my bank account?", "Where does my customer data end up?".

These questions are not only valid – they are necessary. At Replio, we believe that trust is built on transparency, not marketing slogans. That is why we have prepared this exhaustive article in which we "open the hood" and show exactly how our security mechanisms work. We have nothing to hide.

From the very first line of Replio's code, one principle has guided us: First, do no harm. We knew we were building a tool for professionals who have worked for years to achieve Super Seller status. One AI mistake could cost them that status.

That is why security in Replio is not an "add-on" or a "feature". It is the foundation of the entire system's architecture. Before we deploy any new functionality, it undergoes rigorous security audits. If there is even a shadow of a risk to the stability of your account or data security, the feature does not go into production.

Here are the pillars on which our approach is based.

Many fears related to AI stem from the vision of a "black box" that acts on its own, without supervision. At Replio, we consciously rejected the model of full, uncontrolled automation in favor of the Human-in-the-loop model.

The Psychology of Control

As a business owner, you must have control. It is your brand, your voice, and your responsibility. AI is there to support you, not replace you in making key decisions. We treat Replio as an intelligent assistant (Copilot) sitting next to you. It prepares the draft, checks the facts, suggests a solution – but you, as the Captain, give the permission for takeoff.

Operational Scenarios

Let's see how this looks in practice with two examples:

Scenario A: Difficult Dispute A customer opens a dispute claiming the item is damaged and demands a refund, threatening a negative review. Emotions are high.

1. Analysis: Replio analyzes the customer's message (detects negative sentiment), order history (was the package collected?), and your return policy.
2. Strategy: AI does not send a "canned response". It prepares a balanced, professional reply aimed at de-escalating the conflict, proposing a concrete solution consistent with consumer law.
3. Verification: You see this proposal. You might think it's too soft or too formal. You edit one sentence and send it. Result: You saved 15 minutes of nervous writing, and the customer received a professional response. Risk of error: zero, because you approved the content.

Scenario B: Simple Shipping Question A customer asks: "When will you ship the package?".

1. Analysis: Replio checks the order status in the Allegro API. It sees that the label is generated and the courier is scheduled for tomorrow.
2. Suggestion: AI generates: "Good morning! Your package is already packed and waiting for the courier. Estimated delivery is tomorrow/day after tomorrow."
3. Automation (Optional): For such simple, repetitive questions, you can (but don't have to!) enable "Autopilot" mode. Then and only then will Replio send the response itself. But by default – you click "Send".

This is the most important point for many sellers. How is it possible that an application has access to the account but not to the money?

The Magic of OAuth 2.0 and Scopes

Replio connects to Allegro using the official OAuth 2.0 authorization standard. This is the same standard you use when logging in via Google or Facebook to other services. The key feature of this solution is Scopes.

When you connect Replio to Allegro, Allegro displays a list of permissions the application is requesting. This is a closed list. We only ask for:

• allegro:api:messaging:read (reading messages)
• allegro:api:messaging:write (writing messages)
• allegro:api:orders:read (viewing orders)
• allegro:api:offers:read (viewing offers)

What is NOT on this list?

• allegro:api:payments:write (requesting payouts)
• allegro:api:billing:write (changing invoice data)
• allegro:api:profile:write (changing password or email)

Technical Impossibility

Even if we wanted to (and we don't!), or if hackers took over our servers – there is no technical possibility to withdraw even a single cent from your account using the API keys we possess. Allegro will simply reject such a request at the server level, informing that the application does not have the appropriate permissions. This is a "hard" safeguard, independent of us.

API vs Screen Scraping

It is worth being wary of tools that do not use the official API but ask you to provide your Allegro login and password to "pretend" to be a user (so-called screen scraping). Such tools are extremely dangerous because they have full access to everything – including finances. Replio will never ask you for your Allegro password. We use only the secure, official API channel.

Personal data is the currency of the 21st century. Its leak means not only financial penalties but, above all, the loss of customer trust.

Bank-Grade Encryption

All data transmitted between your computer, our servers, and Allegro is encrypted with the TLS 1.3 protocol (successor to SSL). This is the standard used by electronic banking. Even if someone intercepted the data transmission, they would only see a useless string of characters.

Data at rest in our database is also encrypted with the AES-256 algorithm. This means that physically seizing disks from the server room would give an attacker nothing without the encryption keys, which are stored in a separate, secure module (HSM).

Where is Your Data?

We use the cloud infrastructure of world leaders (such as AWS or Google Cloud), with servers located within the European Union. This guarantees compliance with GDPR and physical data security (fire protection, access control, power redundancy).

Data Minimization and AI

Does AI "learn" from my customers' data? This is a common concern. At Replio, we use anonymization mechanisms. Before message content is sent to the language model (LLM) to generate a response, sensitive data (such as personal ID numbers, credit card numbers – although these rarely appear in Allegro messages) are masked. The AI model "sees" the context of the problem but does not need to know the identity of John Doe to propose a solution. Furthermore, according to our agreements with AI providers, your data is not used to train public models. Your know-how stays with you.

Artificial Intelligence itself also has built-in safeguards.

1. Hallucination Detection: Our algorithms verify the AI response before displaying it. If the AI tries to invent a non-existent tracking number or cite a non-existent regulation, the system will flag such a response as requiring special attention or reject it.
2. Sentiment Analysis: The AI is calibrated to always maintain a professional, polite tone. Even if the customer is aggressive and uses profanity, Replio "will not be provoked". The response will always aim to de-escalate the situation. This protects you from escalating a conflict under the influence of emotions.
3. Content Filters: We use filters that block the generation of harmful, offensive, or Allegro policy-violating content.

Q: Do Replio employees read my messages? A: No. Only automated systems have access to your data. Employee access is strictly limited, monitored, and granted only in exceptional technical support situations, solely with your explicit consent.

Q: What happens if Allegro changes its API? A: We are an official technology partner. We have information about changes in advance. Our development team adapts the system on an ongoing basis, so for you, changes are unnoticeable and do not cause service interruptions.

Q: Can I delete my data at any time? A: Yes. In accordance with GDPR, you have the "right to be forgotten". After closing your account in Replio, your data is permanently deleted from our systems within 30 days (this period results from the need to keep backups in case of failure, which are also subsequently overwritten).

Q: Does Replio sell my sales data to competitors? A: Absolutely not. Our business model is based on a subscription for the service, not on trading data. Your sales statistics, bestsellers, and strategies are your trade secret.

Security in e-commerce is not a state, it is a process. It requires constant attention, updates, and the highest standards. At Replio, we have taken this burden off your shoulders.

By choosing us, you are not just choosing a "reply bot". You are choosing an advanced security system that protects your interests, your time, and your money. We give you a powerful weapon in the fight for the customer – artificial intelligence – but equipped with ironclad safeguards and emergency brakes that always remain in your hands.

Sleep soundly. Replio is watching.
