Data Retention Approach

The purpose of this policy is to ensure that necessary data, records and documents of Martian Marketing are adequately protected and maintained. Also, to ensure that records that are no longer needed or are of no value are discarded at the proper time and in the proper fashion. This policy is also for the purpose of aiding employees of Martian Marketing in understanding their obligations in retaining data or electronic documents including email, web files, text files, sound and video files, PDF documents and all Microsoft Office or other formatted files.

In summary, personal data will be retained for no longer than is necessary. A Data Retention Schedule will be produced by Martian Marketing to demonstrate a generic retention period based on the purpose of the data and data retention guidelines. In the event that the retention of personal data is no longer necessary for the operation of Martian Marketing, the data shall be deleted and all copies shall be destroyed as per the defined schedule.


The following Record Retention Schedule is the initial maintenance, retention and disposal schedule for records held by Martian Marketing. This schedule should be reviewed regularly to ensure the data retention policy approach is adhered to.

There are certain occasions when information needs to be preserved beyond any limits set out in the policy. The policy must be SUSPENDED relating to a specific customer or document and the information retained beyond the period specified in this Data Retention Schedule in the following circumstances:

  • Legal proceedings or a regulatory or similar investigation or obligation to produce information are known to be likely, threatened or actual
  • A crime is suspected or detected
  • Information is relevant to a company in liquidation, receivership or where a debt is due to the company
  • Information is considered by the owning unit to be of potential historical importance

In the case of possible or actual legal proceedings, investigations or crimes occurring, the type of information that needs to be retained relates to any that will help or harm the company or the other side’s case, liability or amount involved. If there is any doubt over whether legal proceedings, an investigation or a crime could occur or what information material is relevant in these circumstances, the company shall take such steps as is necessary to promptly inform all staff of any suspension in the further disposal of documents.

The data retention policy is based on the following schedule.

D. Correspondence And Internal Memoranda

General principle: most correspondence and internal memoranda should be retained for the same period as the document to which they relate. For instance, a letter pertaining to a particular contract would be retained as long as the contract (7 years after expiration). It is recommended that records that support a particular project be kept with the project and take on the retention time of that particular project file.

Correspondence or memoranda that do not pertain to documents having a prescribed retention period should generally be discarded sooner. These may be divided into two general categories:

Category 1

Those pertaining to routine matters and having no significant, lasting consequences should be discarded within two years. Some examples include:

  • Routine letters and notes that require no acknowledgement or follow up, such as notes of appreciation, congratulations, letters of transmittal and plans for meetings
  • Form letters that require no follow up
  • Letters of general inquiry and replies that complete a cycle of correspondence
  • Letters or complaints requesting specific action that have no further value after changes are made or action is taken (such as name or address change)
  • Other letters of inconsequential subject matter or that definitely close correspondence to which no further reference will be necessary
  • Chronological correspondence files

Copies of interoffice correspondence and documents where a copy will be in the originating department file should be read and destroyed; unless that information provides a reference to, or direction to other documents and must be kept for project traceability.

Category 2

Those pertaining to non-routine matters or having significant lasting consequences should generally be permanently retained.
