Every contract you sign carries personal data: full name, national ID number, address, phone number, email, and perhaps financial or health data, or a face image when identity verification is used. With the move to digital contracts, this data goes from paper in a locked cabinet to files that travel between email, phones and servers. So data protection in electronic contracts has become both a legal and a commercial matter: legal because Egypt's Personal Data Protection Law No. 151 of 2020 imposes clear obligations, and commercial because customers' trust is quickly shaken by any leak.
In this guide we go through the stages of a contract one by one: drafting, sending, identity verification, signing, storage, sharing and expiry. At each stage we show why it poses a risk to data, how it should be managed, the mistake that recurs in companies, with a practical example. We close with a checklist and frequently asked questions.
Why Are Contracts Among the Most Sensitive Documents?
Contracts bring together on one sheet what entire systems may hold separately: a person's identity, address, financial obligations, and sometimes salary or health condition in employment and insurance contracts. Whoever sees a single employment contract knows more about the employee than most systems do. That is why a leaked folder of contracts is more dangerous than a leaked mailing list, because the data in it is complete, interlinked and exploitable for fraud or identity theft.
In addition, contracts are kept for a long time, because they are evidence of rights. While old marketing lists are deleted, contracts stay for years, and the period of exposure to risk lengthens with them. The common mistake is to treat contracts like any administrative file, kept in a shared folder that all employees can reach. The right approach is to treat them as highly sensitive data with their own permissions.
Stage One: Drafting and Collecting Only the Necessary Data
Data protection begins before the contract is sent, when deciding what to ask of the other party. Every field in the contract is data that will be stored, protected and perhaps asked about. The governing principle here is data minimization: ask for what the contract actually needs to establish identity and perform the obligation, and nothing more.
The right approach is to review the template for each type of contract and ask about each field: does the contract need it legally or practically? A consulting service contract with an individual may need only the name, national ID number, address and email. Asking for date of birth, marital status and number of children has no justification in this contract. The common mistake is copying an old template with all its fields because "that's how it always was."
| Type of contract | Data usually needed | Data often requested without need |
|---|---|---|
| Service contract with an individual | Name, national ID number, address, email, phone | Date of birth, occupation, marital status |
| Employment contract | Personal data, qualification, pay, social insurance data | Religion, family photos, detailed health data |
| Lease | Both parties' details, the leased property, rent and term | Full bank statements for years |
| Confidentiality agreement | Name, capacity and entity | National ID number in every case, even when not needed |
Example: A marketing company asked, in its customer contract, for the front and back of an ID card for every contract, even when the customer was a company represented by its manager. After review it settled for the name, capacity and commercial register number, so it holds less sensitive data without weakening the contract.
Stage Two: Sending the Contract to the Right Party
The biggest source of contract leaks is not hacking but human error: an email sent to the wrong address, a file sent in a WhatsApp group instead of a private chat, or an attachment forwarded to people with no connection. So the way of sending is itself part of data protection.
The right approach is to send the contract through a link specific to the signatory, not as an attached file that is easily forwarded, and to require the signatory to prove that they own the email or phone before seeing the content or before signing. In Wthaiq, each signatory receives their own link, and a one-time verification code is sent to their email or WhatsApp; a secret code can also be added and communicated outside the platform. If the link reaches another person by mistake, they cannot sign.
The common mistake is sending the contract as a file by email and then waiting for a scanned signed copy. With this method the contract multiplies across mailboxes, phones and printers, and nobody knows how many copies exist. Example: A sales employee sends a contract containing one customer's data to another customer with the same first name. Had the sending been through a link that requires a code delivered to the right customer's phone, the wrong recipient could have done nothing.
Stage Three: Verifying Identity Without Collecting Excess Data
Some contracts need confirmation that the signatory is actually the intended person, especially high-value contracts. This is usually done by matching a face image with an identity document. This step strengthens proof, but it means processing sensitive biometric data, so it needs stricter controls.
The right approach is to use identity verification when the size or nature of the contract justifies it, not in every contract, to tell the signatory before starting what will be asked of them and why, and to know who processes this data and where it is stored. In Wthaiq, verification takes place through a specialized external provider, the signatory is shown what will happen before starting, and the contract's sender does not see the ID card image itself in the normal flow.
The common mistake is for a company to ask the signatory to send an image of their ID card and a selfie on WhatsApp, and then an employee compares them by eye. This method is weaker as proof and more dangerous to the data at once, because the images stay on the employee's phone with no control and no deletion period.
Stage Four: Signing and the Audit Trail
At signing, additional data is recorded: the time of signing, the device's network address, the browser type and the verification method. This data is necessary to prove the signature's validity later, but it too is personal data. The balance required is to keep what proof needs, and to tell the signatory that this data is recorded and for what purpose.
The audit trail itself is a tool for protecting data, not a burden on it. It shows who opened the contract and when, so if someone claims they never saw the contract or that someone else signed in their name, the log is the arbiter. In Wthaiq, a log of events is kept for each contract: sending, opening, sending the code, verification and signing, with a trusted timestamp fixing the time of signing.
Example: A signatory denies two months later that he signed a supply contract. The log is produced: the link was opened from his device, the code was sent to his registered phone number, the correct code was entered, and he signed at a specific time fixed by a timestamp. This proof needs no extra data, only disciplined recording of what happened.
Stage Five: Storage and Permissions
After signing, the contract enters a long storage period, and this is where most of the risks lie. A contract kept in a shared folder, in an employee's email or on his phone is exposed to unauthorized access for years. The right approach is to store contracts in one place and to set permissions so that each employee sees only what their work needs.
| Role | What they need to see | What they do not need to see |
|---|---|---|
| Sales representative | His customers' contracts | Employment contracts and colleagues' contracts |
| HR employee | Employees' contracts | Customer and supplier contracts |
| Accountant | Amounts and payment dates | Full identity details |
| Manager | All contracts as needed | — |
In Wthaiq, team members' roles and permissions are set, and sending a contract can require a manager's approval before it goes out. The common mistake is giving every employee the same manager account to make work easier, so the ability to know who did what is lost. Example: A company discovered that an intern could see the senior management's salary contracts because the whole team logged in with one account. After roles were distributed, access was confined to HR.
Stage Six: Sharing with External Parties
A company may need to share a contract with a lawyer, an auditor or a financing body. Every share means the data moves to a new party. The right approach is to share only what is needed, to prefer a limited viewing link over sending the whole file, and to make sure the receiving party is bound by confidentiality.
A suggested clause in the contract: "The parties acknowledge that the personal data contained in this contract is processed for the purpose of concluding, performing and proving it, and neither of them may disclose it to anyone other than its professional advisers who are bound by confidentiality, or the competent authorities in accordance with the law."
The common mistake is sending the entire contracts folder to the auditor when he needs a sample of it. The right approach is to define the sample required and send only that.
Stage Seven: Contract Expiry and Retention Period
The end of a contract does not mean deleting it immediately, because it may be needed to prove rights or claims within limitation periods. But neither does it mean keeping it forever. The right approach is for the company to set a written retention policy that specifies a period for each type of contract, consulting a specialist on the appropriate periods, and to delete what has exceeded the period through a documented procedure.
The distinction between the contract itself and accompanying data matters. The signed contract and its audit trail may be kept as evidence, while marketing data or correspondence with no evidentiary value is deleted. Example: A telecom company keeps expired subscription contracts for a period sufficient for claims, then deletes the former customer's marketing contact data as soon as the relationship ends, unless he agrees to keep receiving offers.
Informing the Signatory: Transparency Is Part of Protection
One of the simplest means of compliance, and the most neglected, is to tell the signatory what happens to their data. Two clear lines in the invitation message or on the signing page, stating the purpose of collecting the data, how long it is kept, and how to contact the company, raise trust and reduce complaints.
A suggested wording for a line on the signing page: "Your data is used in this contract to conclude it and prove your signature, and the time of signing and the verification method are recorded for this purpose. For any inquiry about your data, you may contact us at the address stated in the privacy policy."
The common mistake is leaving the privacy policy as a hidden link at the bottom of the site, which the signatory does not reach at the moment of signing.
A Data Protection Clause Within the Contract Itself
It is not enough to protect data in how a contract is sent and stored; it is advisable for the contract itself to state how data exchanged between the parties is handled, especially in service and supply contracts in which one party receives the other's customers' or employees' data. A technical support company that reaches its client's database, and a shipping company that receives buyers' addresses, both process personal data on behalf of others, and the contract should define the limits of that.
The right approach is for the contract to include a clause that defines the purpose of processing, obliges the receiving party to secure the data and not to use it for its own purposes, to report any breach, and to return or delete the data when the relationship ends. The common mistake is to settle for a general confidentiality clause that does not mention personal data or what happens to it after the contract ends. Example: An e-commerce company contracted with a shipping company without a data clause, and after the contract was terminated, thousands of customers' addresses remained with the former company with no obligation to delete them.
The Role of the Platform and the Role of the Company
It is important to be clear that the signing platform is a processor working on the company's behalf, and the company remains the controller responsible for the data. The platform provides tools: private links, verification codes, permissions, an audit trail and a timestamp. But the decision on what is collected, who sees it, and the retention period remains the company's decision. The common mistake is for a company to think that choosing a good platform exempts it from setting its own policy.
The right approach is to choose a platform that provides the necessary tools, to review its terms and its position on data, and then to build your internal policy on top of it: who sends, who approves, who sees, and when it is deleted.
A Checklist for Data Protection in Your Contracts
- Does each contract template request only the necessary data?
- Are contracts sent by private links, not open attachments?
- Is the signatory required to prove ownership of the email or phone before signing?
- Is identity verification used only where the contract justifies it, with the signatory informed?
- Is an audit trail kept for each contract?
- Are contracts stored in one place with defined permissions?
- Does each team member have their own account and role?
- Is there a written policy for retention periods and deletion?
- Is the signatory told the purpose of collecting their data?
Frequently Asked Questions
Is electronic signing less secure for data than paper?
Not necessarily. A paper contract moves between hands, is photographed and sent scanned, and there is no record of who saw it. An electronic contract managed in a single platform can have its permissions controlled and every view recorded.
Must the national ID number be requested in every contract?
No. It is requested when the contract needs it to identify the party or for legal purposes. In many cases the name, capacity and contact details are enough.
Who owns the signatories' data on a signing platform?
The sending company is the controller of its signatories' data, and the platform processes it on its behalf to provide the service. The platform's terms should make this clear.
Can a signatory ask for his data to be deleted after signing?
He may ask, but the signed contract and the record that proves it may be kept if they are needed to prove rights, with him informed of that and anything unnecessary deleted.
Is sending a contract on WhatsApp secure?
Sending the file itself on WhatsApp lets it spread without control. Sending a private signing link or a verification code through WhatsApp is a practical method, because the content stays on the platform and only the number's owner can sign.
Conclusion
Data protection in electronic contracts is not a single step, but a series of small decisions at each stage: what you ask for, how you send it, who sees it, and when you delete it. A company that controls this chain protects its customers and itself at the same time. Start by sending your contracts through Wthaiq with private links, verification codes, a complete audit trail and clear team permissions.
