The purpose of this guide
The Office of the Australian Information Commissioner (OAIC) has developed this guide to help mobile device application (app) developers embed better privacy practices in their products and services, and help developers that are operating in the Australian market to comply with Australian privacy law and best practice.
Many of the practices outlined in this guide may also assist other businesses involved in the app ecosystem, such as:
- advertising networks
- mobile platform providers
- app developer trade associations
- developers of other (non-mobile) applications.
This document is a better practice guide. It is designed to provide suggestions for both privacy compliance and better practice. Your business may or may not be covered by the Privacy Act 1988. Whether it is or not, this guide will help you make your apps more privacy-friendly.
There is a checklist to help you ensure your app is privacy friendly at Appendix A. The checklist is a summary of this guide. You can follow the checklist to help build privacy protections into your apps. There is also a list of resources at Appendix B if you need more information.
People are increasingly using mobile devices for their computing needs, including to access the internet. In a 2012 Australian study:
- 76 per cent of respondents said that they owned a smartphone, compared with 67 per cent in 2011
- 84 per cent of respondents said that they would own a smartphone in 2013
- 69 per cent of the mobile phone users — and 87 per cent of smartphone users — had installed an app on their phone
- 38 per cent said that they owned a ‘tablet’ device
- 92 per cent of tablet owners said that they used apps on their device.
The Australian community puts a high level of trust in the mobile apps they use and their expectation for privacy protection is equally high. Apps that fail to protect user privacy lose user confidence and gain negative publicity.
Failing to protect privacy could also result in a breach of the Privacy Act (see Application of the Privacy Act, below). Individuals can complain to the OAIC if they believe that their privacy has been breached by a business or government agency covered by the Act. Alternatively, the Information Commissioner can choose to investigate the way in which your app handles personal information, even if no-one has complained. The consequences of an investigation could include having to change the way your app handles personal information or having to pay compensation to affected users. Where a breach of privacy is very serious, the Commissioner may seek a civil penalty.
Privacy by design
The mobile environment, along with the new app economy it has generated, presents both potential and risks for how personal information is handled. If you are a mobile app developer, whether you work on your own, or for a business or government agency, you should adopt a ‘privacy by design’ (PBD) approach. PBD aims at building privacy and data protection up front, into the design specifications and architecture of information and communication systems and technologies, in order to facilitate compliance with privacy and data protection principles.
You can build PBD into your apps by applying privacy-enhancing practices throughout the life cycle of the personal information that you handle — that is, its collection, use (including data matching, targeted advertising and analytics), disclosure, storage and destruction. Given the growing popularity of apps, app developers can expect increased scrutiny of the privacy practices in the app industry in the years ahead — by both regulators and the market itself, driven by increasingly informed, discerning and influential consumers. Implementing a PBD approach will help you make sure you are privacy-friendly, whether or not your business is covered by the Privacy Act.
If your business must comply with the Privacy Act, implementing better privacy practice can also reduce your compliance costs.
How does the Privacy Act apply to apps and app developers?
What is personal information?
The Privacy Act regulates the way in which individuals’ personal information is handled.
Personal information is information or an opinion about an identified individual, or an individual who is reasonably identifiable. What constitutes personal information will vary, depending on whether an individual is reasonably identifiable in a particular circumstance, but may include:
- Internet Protocol (IP) addresses, Unique Device Identifiers (UDIDs) and other unique identifiers in specific circumstances
- contact lists, which reveal details about the contacts themselves and also a user’s social connections
- voice print and facial recognition biometrics, because they collect characteristics that make an individual’s voice or face unique
- location information, because it can reveal user activity patterns and habits.
Application of the Privacy Act
The Australian Privacy Principles (APPs) in the Privacy Act set out how personal information should be handled. The APPs apply to most Australian and Norfolk Island Government agencies and some private sector organisations – collectively referred to as APP entities.
All businesses and not-for-profit organisations with an annual turnover greater than $3 million have responsibilities under the Privacy Act subject to some exceptions.
As well some small business operators (organisations with a turnover of $3 million or less) are covered by the Privacy Act including:
- private sector health service providers
- businesses that sell or purchase personal information
- credit reporting bodies.
You are likely to be covered by the Privacy Act if you use personal information to sell advertising, including through an app.
The APPs cover the collection, use, disclosure and storage of personal information. They allow individuals to access their personal information and have it corrected if it is incorrect. There are also specific APPs that deal with the use and disclosure of personal information for the purpose of direct marketing (APP 7) and cross-border disclosure of personal information (APP 8). Implementing the steps in this guide will help you to comply with the current principles and the APPs.
If your business is covered by the Privacy Act, it is important that you understand whether your app is used for direct marketing and make sure it complies with the direct marketing requirements of APP 7.
Make user privacy your competitive advantage
Whether or not you are covered by the Privacy Act, as an app developer, it’s ultimately in your best interests to build strong privacy protections into your apps. The mobile apps that take privacy seriously will be the ones that stand out from the crowd and gain user trust and loyalty:
- The 2013 OAIC Community Attitudes to Privacy study found that 62 per cent of Australians opt not to use smartphone apps because of concerns about the way personal information would be used.
- A 2013 survey by the Pew Research Centre found that 51 per cent of teenage app users had avoided certain apps over privacy concerns, and 26 per cent had uninstalled an app because it was collecting personal information that they did not wish to share.
- A 2012 Australian study found that 56 per cent of Australians do not approve of websites showing specific advertising based on information that the websites have collected in the background about their interests. Further, 69 per cent of respondents reported they had refused to use an application or website because it collected too much personal information. 75 per cent of the respondents said they needed to know more about the ways in which companies collected personal information.
App privacy essentials
This section covers the essential information you need to know when designing, implementing and managing your app. There is a checklist to help you ensure your app is privacy friendly at Appendix A. Remember — think ‘privacy by design’!
1. Your privacy responsibilities
It is important to integrate good privacy protections into your day-to-day business practice. You should also ensure that your business arrangements and contracts protect privacy and comply with your obligations under the Privacy Act.
APP 1 requires APP entities to take reasonable steps to implement practices, procedures and systems that enable compliance with the APPs, and will enable them to deal with privacy enquiries or complaints.
Putting in place a privacy management program for your business will help you manage risks up front. Given the potentially high number of users of your app, it can also help you to respond to requests for access to their personal information and complaints in an organised manner.
Developing and managing your privacy management program
Managing privacy doesn’t need to be complicated or difficult. Anyone, from a one-person operation to a large company, can build a privacy management program.
- Identify someone within your business to be responsible for privacy protection and dealing with privacy complaints, even if you only have a small team.
- When you are in the planning stages for an app, conduct a Privacy Impact Assessment (PIA) to help ensure you have considered all the relevant privacy issues (see below for more information).
- Have controls in place (such as contracts) to ensure that third parties process personal information in accordance with their obligations under privacy law and facilitate your compliance with your own obligations, and make sure the controls are aligned with user expectations. Be cautious when using third party code or software development kits — such as those from advertising networks or analytics providers – which could contain code you aren’t aware of, such as aggressive adware or malware. A PIA can help establish what kind of controls may be appropriate.
Privacy impact assessments
You should consider carrying out a PIA for each app you develop, whether or not your business is covered by the Privacy Act.
A PIA is a tool that ‘tells the story’ of a project from a privacy perspective. A PIA:
- describes how personal information ‘flows’ in a project — how it is collected, used, disclosed, accessed, stored and deleted
- analyses the possible privacy impacts of the project on individual privacy
- through that analysis, helps find potential ways to manage, minimise, or avoid privacy impacts while achieving or enhancing project goals
- encourages good privacy practice and underpins good risk management.
You may choose to publish your PIA so that members of the public are aware of your commitment to privacy. You might even wish to encourage privacy organisations or members of the public to consult on your draft PIA. Both actions will help build user trust in your app.
The OAIC has published a Guide to undertaking privacy impact assessments which you may find useful. Additional resources and tools can be found in Appendix B.
2. Be open and transparent about your privacy practices
- who you are and how to contact you
- what kinds of personal information your app collects and stores
- how your apps collects personal information, and where it will be stored (on the device or elsewhere)
- the purposes for which your app collects the personal information
- how personal information will be used and disclosed
- how users may access their personal information, and correct it or seek to have it corrected
- how users may complain about a breach of the APPs, and how you will deal with such a complaint
- whether you are likely to disclose the information outside Australia and, if it is practicable, which countries you are likely to disclose the information to.
Sending information overseas
APP 8 imposes specific obligations about sending personal information outside of Australia and you may remain accountable for what happens to that information. If your app sends your customers’ personal information overseas, you should make sure that the personal information is still handled in a way which protects your customers’ privacy.
As a matter of best practice, you may also want to tell users
- how long you will keep the personal information that your app collects
- whether the users will be ‘trading’ access to their personal information for benefits such as convenience or free downloads, and
- any other issues that will affect user privacy.
- Give users reasonable time to provide feedback before you implement changes.
- Tell users exactly what rules you are changing so they don’t have to compare the new and old policies to understand what’s happening.
- If you are including new features, especially features that involve disclosing information to third parties, make the changes easy to find and understand through the update process.
- Wherever possible, seek express consent from users to any changes that could impact on their privacy.
- Never make silent app updates that will diminish the user’s privacy.
If your app collects sensitive information, you are likely to have additional privacy obligations under the APPs. ‘Sensitive information’ includes an individual’s health information, their membership of a trade union or political association, their sexual orientation or practices, and more.
3. Obtain meaningful consent — the small screen challenge
Your customers need to know about your privacy practices to be able to provide you with informed consent to handle their personal information — but it can be difficult and unpleasant to read a lengthy privacy notice on a small screen. Getting the balance right between providing information and avoiding ‘notice fatigue’ (where people ignore notices or warnings because of over-exposure) is critical. We list some suggestions below.
Use short form notices
- Provide specific, targeted notices to users when they need to make a decision about whether to consent to the collection of their personal information. These notices should details about the specific collection so that users can make an informed decision.
- Make sure that the short form notice draws user attention particularly to any collection, use or disclosure of information that they would not otherwise reasonably expect.
Provide a privacy dashboard
- Display user privacy settings with a tool that allows users to tighten their settings. The tool should be easy and straightforward to use.
- Instead of just using an on/off button, explain the consequences of making a choice to provide data so users can make an informed decision.
- See Resources in Appendix B – but make sure the result meets any obligations you have in Australia under the Privacy Act.
- You could also make use of graphics in the app at the moment when sensitive information is about to be transmitted and user consent is required. For example, if your app is about to access the user’s location data, you could activate a symbol or icon to raise user awareness of what is happening and the reason for it, as well as the user’s choices.
- You can alert the user by using colour and altering its intensity. The intensity of the colour could be scaled to the importance of the decision or sensitivity of the information.
- Selective use of sounds, and scaling the device’s volume, can draw attention to a privacy-related decision that needs to be made in a timely way.
For further information, including on the use of symbols and icons, see Communicating privacy rules on small screens in Appendix B.

4. Timing of user notice and consent is critical
When people use mobile devices, their attention can be intermittent and limited. So it’s important to be thoughtful and creative about the timing of user notice and consent. To get the most impact, consider the following:
- Highlight privacy practices during the download/purchase process and also upon first use.
- Obtain consent at the point of download.
- Tell users what will happen with their information in real time — this is sometimes known as providing ‘in-context notices’. Users must be able to make timely and meaningful choices. For example, if your app takes photos or video, the first time that the user activates the photo or video function, clearly state if your app will tag the images with location data and allow the user to opt out of this feature.
5. Only collect personal information that your app needs to function
The APPs requires that you only collect the personal information that is necessary. Consider whether you need to collect personal information at all.
- If you cannot explain how a piece of personal information is related to the functions or activities of your app, then you probably should not be collecting it. Don’t collect personal information just because you believe it may be useful in the future.
- Delete or de-identify personal information that you no longer need for a lawful purpose.
- As best practice, allow users to opt in to the collection or use of their personal information. If that is not practicable, allow users to opt out of data collection. If you cannot enable users to opt in or out, explain this to users first so they can make an informed decision about whether to install your app.
- Don’t collect sensitive information about a user at all, unless the user has expressly consented.
- Avoid collecting information about a user’s movements and activities through the use of integrated location and movement sensors unless it relates directly to the app and you have the user’s informed consent.
- Don’t collect sound or activate the device camera without the specific permission of the user.
- It is best privacy practice not to collect and store personal information about third parties from a user’s device unless you can obtain the consent of those parties. For example, do not collect and store your user’s address book.
- Apps should be designed in a way that does not require you to collect any persistent identifiers if it is not essential to the functioning of the app.
- Avoid associating personal information across apps, or between your app and a user’s social media account, unless it is obvious to the user and necessary to do so. If you must make links, ensure that personal information is not linked to a user’s identifier for longer than it needs to be. For example, if your app transmits personal information, you should not keep a copy of it unless it is necessary.
- Allow users to change their minds about giving you access to their personal information. If this means that they have to uninstall the app, explain this clearly and simply.
6. Secure what you collect
The APPs require you to take reasonable steps to protect any personal information you hold from misuse, interference and loss, as well as unauthorised access, modification or disclosure.
- Make someone in your business responsible for security.
- Have appropriate controls in place both on the mobile device and on the backend systems to store personal information securely. For example, you should encrypt user information when it is transferred via the internet or stored.
- Adapt your code to allow for differences in mobile platforms.
- Generate credentials securely.
- Do your due diligence on libraries and other third-party code.
- Don’t store passwords in plain text on your server.
- Give users the ability to request the deletion of all of the personal information about them that your app has collected.
- Prepare, implement and regularly update a data breach policy and response plan.
See the OAIC’s Guide to information security and Data breach notification - A guide to handling personal information security breaches.
A data breach is when personal information your app holds is lost or subjected to unauthorised access, use, modification, disclosure or other misuse. If you experience a data breach connected with your app, you may need to inform your users.
Appendix A — Privacy and mobile apps: a checklist for app developers
Your privacy responsibilities
Your agency or organisation (which may just be you) is responsible for all personal information collected, used and disclosed by your mobile app.
Identify someone to be responsible for privacy protection.
Use a Privacy Impact Assessment to map where the information is going, identify potential privacy risks, and assist with privacy planning (including ‘privacy by design’).
Implement practices, procedures and systems that enable compliance with the Australian Privacy Principles, and will enable you to deal with privacy enquiries or complaints.
Put in place controls, such as conditions of contract or user agreements, to ensure that third parties accessing personal information through your app respect their privacy obligations.
Be open and transparent about your privacy practices
When updating an app, inform users of any changes to the way their personal information is handled, and seek express consent to any changes that could impact on their privacy.
Obtain meaningful consent despite the small screen challenge
Select the right strategy to convey privacy rules in a way that is meaningful on the small screen. This could include:
‘short form notices’, with important points up front and links to more detailed explanations
a privacy dashboard that displays a user’s privacy settings and provides a convenient means of changing them
cues such as graphics, colour and sound to draw user attention to what is happening with their personal information, the reasons for it, and choices available to the user.
Timing of user notice and consent is critical
Obtain consent at the point of download.
Tell users how their personal information is being handled at the time they download the app and in-context when they use the app to ensure that their consent is meaningful and relevant.
Consider how best to deliver privacy messages to most effectively capture users’ attention and achieve the most impact at the right time, without causing notice fatigue.
Only collect personal information that your app needs to function
Limit data collection to what is needed to carry out legitimate purposes.
Do not collect data just because you think it may be useful in the future.
Allow users to opt out of the collection of their personal information, or if that is not practicable, clearly explain they cannot opt out so they can make an informed decision whether to use the app.
Delete or de-identify personal information that you no longer need for a lawful purpose.
Secure what you collect
Put in place appropriate safeguards to protect the personal information you are handling. Use encryption when storing and transmitting data.
Give users the ability to delete or request the deletion of all of the data that your app has collected about them.
Publish clear policies about how long it will take to delete personal information once a user stops using your app.
Delete personal information that you no longer need for a lawful purpose.
