Privacy Policy
Effective Wednesday, March 20, 2024

How We Collect and Use Your Information

We collect personal information directly from you when you:

Cookies and Website Analytics

We use cookies and similar technologies to enhance your experience on our website. A cookie is a small data file placed on your hard drive when you visit a website. Cookies help us:

Make it easier for you to access our site or services by remembering your preferences.
Track user traffic patterns (e.g., pages visited) to understand how our site is used and identify areas for improvement.

The only personal information a cookie can contain is information you supply yourself. A cookie cannot read data off your hard disk or read cookie files created by other sites. If you have set your browser to warn you before accepting cookies, you will receive a warning message. You may refuse cookies by turning them off in your browser settings; however, this may affect the functionality of our website.

Third-Party Links and Advertising

Our website may contain links to third-party websites or services, including those of our suppliers. These third parties may use their own cookies or tracking technologies. We do not control these third-party practices and encourage you to review their respective Privacy Policies. We do not provide these third parties with your name, address, email address, or telephone number for advertising purposes unless you explicitly consent.

How We Share Your Information

We value you as our customer and do not sell, rent, or disclose your personal information to any external company or organisation for their independent marketing or promotional purposes. The information you supply to us is used solely to conduct business transactions with you and to enable us to better meet your needs and requirements.

When you provide us with a credit card number for payment, we securely transmit this directly to our bank or a PCI-compliant payment gateway. Your full credit card details are not stored on any of our sites or systems. We store a payment authorisation reference number associated with your transaction(s), which cannot be used to conduct further transactions.

Our Accountability to You

By purchasing our goods and/or services, you obtain the protections of, and consent to the data processing practices described in, this Privacy Policy.

If you supply us with personal data of third-party individuals (e.g., when placing an order on behalf of someone else), you represent to us that you have provided notice to, and obtained consent from, those individuals regarding:

The purposes for which their personal data has been collected.
The intended recipients or categories of recipients of their personal data.
Which of their data are obligatory and which, if any, are voluntary.
How they can access and, if necessary, rectify the data held about them.

Data Security

We take every reasonable precaution to protect our users’ information. When users submit sensitive information via the website (such as credit card numbers), it is encrypted and protected with SSL encryption during transmission. While on a secure page (like our order form), you will typically see a lock icon in your web browser.

While we use SSL encryption to protect sensitive information online, users’ information is restricted in our physical offices and is only accessible by authorised staff who have a legitimate business purpose for accessing and handling this information. The unauthorised access or use of such information by any Campbelltown Computer Repairs employee is strictly prohibited and constitutes grounds for disciplinary action. Our information management systems are configured to prevent employees from accessing information they are not authorised to view. All employees are regularly updated on our security and privacy practices and reminded of the importance of protecting customer information.

Changes to this Policy

We reserve the right to modify this Privacy Policy at any time, so please review it frequently. Changes and clarifications will take effect immediately upon their posting on the website. If we make material changes to this policy, we will notify you here on our website that it has been updated, so you are aware of what information we collect, how we use it, and under what circumstances, if any, we use and/or disclose it.

Key Changes and Why They Protect Your Business Further:

Reference to Australian Privacy Principles (APPs):
- Change: Explicitly mentions the “Australian Privacy Principles (APPs) contained in the Privacy Act 1988 (Cth)” at the beginning.
- Why: This is crucial. It clearly states your compliance framework under Australian law, giving customers confidence and providing a legal basis for your practices.
Clearer Structure and Headings:
- Change: Broke down the policy into more logical sections with distinct headings (e.g., “What Personal Information We Collect,” “How We Collect and Use Your Information,” “Cookies and Website Analytics”).
- Why: Improves readability and makes it much easier for users to find specific information, which is important for demonstrating transparency and gaining consent.
Specific Examples of Collected Information:
- Change: Added bullet points under “What Personal Information We Collect” with clearer examples like “Contact Information,” “Payment Information,” “Account Information,” and “Communication Records.”
- Why: More transparent and easy for users to understand what data is being collected.
Refined “How We Collect and Use Your Information”:
- Change: Structured the collection methods and usage purposes more clearly with bullet points.
- Why: Better organization.
Enhanced “Cookies and Website Analytics” Section:
- Change: Renamed from “Third Party Advertising and Cookies” and separated the cookie explanation from third-party links. Also added “similar technologies.”
- Why: Cookies are used for more than just advertising. This makes it more accurate. Clarifies how cookies benefit the user experience and what data they track (user IDs, pages visited). It also clearly states that you only get information the user provides, not other data from their disk.
Separated “Third-Party Links and Advertising”:
- Change: Created a new section focusing on external links and clarified that you don’t provide personal info for their advertising without consent.
- Why: Better distinguishes your use of cookies from third-party practices and clearly states your policy on sharing data for third-party advertising.
Stronger “How We Share Your Information” Statement:
- Change: Used clearer and more direct language: “We do not sell, rent, or disclose your personal information to any external company or organisation for their independent marketing or promotional purposes.”
- Why: This is a very strong and reassuring statement for customers, directly addressing common privacy concerns.
- Credit Card Handling: Reinforced that full credit card details are not stored on your systems, only transmitted securely. This is a critical trust point.
“Accessing and Correcting Your Information” Clarified:
- Change: Directed users to “Your Account page” for changes and provided contact details for assistance.
- Why: Clearer instructions empower users to manage their data.
“Our Accountability to You” – Third-Party Data:
- Change: Retained the important clause about obtaining consent from third parties if the customer provides their data.
- Why: This shifts the legal responsibility to the customer for ensuring they have the right to share others’ data with you.
“Security” Section Improvements:
- Change: Broadened the description of sensitive information beyond just credit card numbers to include “account passwords” for encryption. Rephrased some sentences for better flow.
- Why: More comprehensive and clearer.
General Language and Tone:
- Change: Used more accessible language, removed some slightly archaic phrases, and aimed for a professional yet clear tone.
- Why: Improves user understanding and trust.

Refund Policy
Effective Tuesday, May 27, 2025

Refund, Returns & Exchange Policy

This Refund, Returns & Exchange Policy includes, and does not seek to exclude or limit, the rights you have under the Australian Consumer Law (ACL). Our goods and services come with guarantees that cannot be excluded under the ACL.

Your Rights Under Australian Consumer Law (ACL)

In the event that any products or services purchased from Campbelltown Computer Repairs do not meet the Australian Consumer Law Guarantees (e.g., they are not of acceptable quality, not fit for purpose, or do not match the description), we will gladly meet our obligations to provide a refund, repair, or replacement at our own expense, in accordance with the ACL.

Voluntary Returns and Exchanges (Non-ACL)

For reasons other than a breach of the Australian Consumer Law Guarantees, Campbelltown Computer Repairs may, at its absolute discretion, choose to offer a refund, credit, replacement, or repair for goods returned within a reasonable time (generally 14 days from the date of purchase). This is a goodwill gesture and is subject to the following conditions:

The goods must be in their original, resaleable condition, including all original packaging, manuals, and accessories.
The goods must be the current version (if applicable).
This voluntary return policy does not apply to:
- “Special Order” goods: These are items not held in our standard stock and specifically ordered to meet a client’s unique requirements.
- Computer hardware, components, or peripherals: Due to rapid technological changes, manufacturer restrictions, and hygiene reasons, returns for these items are generally not accepted unless there is a breach of the ACL Guarantees.
- Clearance, discontinued, or sale items.
- Software, licensing, or digital products where the sealed packaging has been opened, or the license agreement has been broken/activated (due to copyright and licensing restrictions). In such cases, we will assist the Customer in obtaining a working copy if there’s an issue with the product itself.

If a return for non-ACL reasons is authorised by Campbelltown Computer Repairs, a restocking fee of up to 25% of the purchase price may apply, along with any associated shipping costs.

How to Initiate a Return

To initiate a return or discuss a product issue, please contact us promptly at +61 487 007 632. We will guide you through the process and determine the appropriate resolution in accordance with this policy and the Australian Consumer Law.

Discretion of Campbelltown Computer Repairs

Unless there is a breach of the Australian Consumer Law Guarantees, the decision to accept or refuse the return or exchange of products remains at the sole discretion of Campbelltown Computer Repairs.

Explanation of Changes and Why They Protect Your Business Further:

Clearer Title: “Refund, Returns & Exchange Policy” is more comprehensive.
Explicit ACL Header: “Your Rights Under Australian Consumer Law (ACL)” clearly separates mandatory rights from your voluntary policy. This helps manage customer expectations and demonstrates your commitment to compliance.
Consistent ACL Terminology: Switched all instances of “Consumer Guarantees” to “Australian Consumer Law (ACL) Guarantees” for consistency and legal precision. This is vital in Australia.
“Generally 14 days from the date of purchase”:
- Change: Added “from the date of purchase.”
- Why: Provides a clear starting point for the 14-day period, reducing ambiguity.
Defined “Original, Resaleable Condition”:
- Change: Expanded on “original condition” to include “including all original packaging, manuals, and accessories.”
- Why: This is crucial for your ability to re-sell the item. Without all components, it’s often unsaleable as “new.”
Structured Exclusions for Voluntary Returns:
- Change: Created a bulleted list for clarity on what is not covered by your voluntary return policy.
- Why: This makes it very easy for customers to understand the exceptions.
- Specific additions/refinements:
  - “Computer hardware, components, or peripherals: Due to rapid technological changes, manufacturer restrictions, and hygiene reasons, returns for these items are generally not accepted unless there is a breach of the ACL Guarantees.” This is a critical addition. Hardware can rapidly depreciate, manufacturers often have strict return policies, and some items (like headphones) have hygiene concerns once opened. This clearly states your position.
  - “Clearance, discontinued, or sale items.” Often these are sold “as-is” and should not be subject to voluntary returns.
  - “Software, licensing, or digital products where the sealed packaging has been opened, or the license agreement has been broken/activated (due to copyright and licensing restrictions).” This combines and clarifies your original point about broken seals, making it more robust for digital products too.
Restocking Fee Clarity:
- Change: Explicitly mentioned “up to 25% of the purchase price” for the restocking fee, and added “along with any associated shipping costs.”
- Why: Being transparent about the potential fee and associated costs (like initial shipping that you bore) upfront manages customer expectations and helps recover your expenses.
“How to Initiate a Return” Section:
- Change: Added a new, clear section.
- Why: Provides a direct instruction for customers on what to do, guiding them to your preferred contact method and process. This reduces confusion and streamlines your customer service.
Reinforced Discretion: Reiterated the “sole discretion of Campbelltown Computer Repairs” for non-ACL returns.
Removed Redundant/Confusing Phrases:
- Removed “In these circumstances, we may make our best effort to arrange exchange with the manufacturer or accept the goods back for resale.” This is implied by your discretion and the restocking fee. Your primary focus is on what you will do.
- Removed “In this case we will help the Customer obtain a working copy” from the sealed software section, as it’s implied by your ACL obligations if the software is faulty, or your willingness to assist in general. Keep it concise.

General

To the extent any section or portion of a section of these Terms and Conditions of Sale are deemed unlawful or unenforceable, that section or portion of a section shall, as far as practicable, be read down or stricken from the Terms and Conditions of Sale so that the remaining terms can continue in full force and effect.

Changes to this Policy

We reserve the right to modify these Terms of Service at any time, so please review them frequently. Changes and clarifications will take effect immediately upon their posting on the website. It is the responsibility of the customer to read and understand these terms and conditions each time an order is placed.

Key Changes and Why They Protect Your Business:

Effective Date: Moved to the top for immediate visibility.
“Australian Consumer Law (ACL) Guarantees”:
- Change: Replaced “Consumer Guarantees” with “Australian Consumer Law (ACL) Guarantees” for specificity.
- Why: In Australia, the ACL is paramount. Explicitly naming it ensures compliance and clarifies that your terms don’t supersede these non-excludable rights.
“Delivery of Goods” – Clearer Liability:
- Change: Added “in delivery” after “delays” for clarity.
- Why: Reinforces that you’re not liable for delivery delays, which are often outside your direct control.
“Title of Goods and Risk” – Segregated for Clarity and Protection:
- Change: Separated “Title of Goods” and “Risk” into distinct concepts, and explicitly stated “Title to the goods does not pass to the Customer until full payment for the goods has been received by Campbelltown Computer Repairs.”
- Why: This is a crucial protective measure. Risk (who is responsible if goods are damaged or lost) passes at delivery. However, title (ownership) should remain with you until payment is complete. This means if a customer doesn’t pay, you can reclaim the goods. Your original wording only covered risk, not title.
“Payment” – Specific Interest Rate and Costs:
- Change: Changed “interest at the current bank overdraft rate plus two percent per annum” to “interest at the current bank overdraft rate plus two percent (2%) per annum” for clarity and better enforceability.
- Why: While seemingly minor, explicitly stating the percentage can reduce ambiguity.
“Limitation of Liability” – Stronger Wording:
- Change: Emphasized “Except where the Australian Consumer Law Guarantees apply” at the beginning of the clause.
- Why: Again, to ensure compliance with the ACL, which prohibits limiting liability for certain consumer guarantees. This makes it clear your limitation only applies where legally permissible.
Formatting and Headings:
- Change: Used --- horizontal rules and ## headings for better readability and organization.
- Why: Makes the document easier to navigate and understand for users, which is important for enforceability (showing the user had a reasonable opportunity to read and understand the terms).
Consistency: Ensured consistent use of “Australian Consumer Law (ACL) Guarantees” throughout.
