A terrifying anonymous letter telling the founder of a not-for-profit to 'watch your back ' also included threats against the woman 's daughter , claiming they knew where she went to school . Lordina Jane , President and Founder of Palm Oil Investigations ( POI ) discovered the harrowing letter on Tuesday , ahead of the release of the POI app on Wednesday evening . The free app - developed by the not-for-profit over the past 12 months - will inform consumers about the palm oil content of the products available on supermarket shelves . 'When I opened that letter I went cold ... I took the letter and went straight to the police , ' Lorinda told Daily Mail Australia . This anonymous letter was sent to Palm Oil Investigations ( POI ) President Lorina Jane threatening her , and her daughter and claiming to know where they live . 'It 's a really gutless thing to do ... The person who sent it has been that gutless they would n't put their name to it . ' Lorinda is the founder and president of the not-for-profit which provides information to consumers about products that contain palm oil . Coming from an anonymous source , the letter made claims that should their company feature 'unfavourably ' in the new app , 'we will be your worst enemy ' . 'We know you are soon to release a phone app about products with palm oil in , ' the letter began . 'If our company is listed unfavourably we will be your worst enemy . 'If our listing has a negative effect on our company , we know where you live , we know you have a daughter and we know where she goes to school . You will both need to watch your back , ' it continued . 'You have bragged online that your app will be a ‘ game changer ’ , it well may be only not how you expect , ' the letter concluded , . Lorinda said in the years since the POI launched their Facebook page - which has over 144,000 'likes ' - they have never encouraged any consumers to boycott particular brands , but are about simply providing information . The letter , which was printed and not handwritten , and featured no company markings , is the first of its kind according to the POI founder . Lorinda believes it could have come from a smaller brand they have contacted in the process of putting together their app - which acts as a barcode scanner and puts products into five categories . The threats came a day ahead of the release of the POI app , which aims to inform consumers about the palm oil content of the products they consume . The first category is palm oil free , the second indicates the company has signed on to stop deforestation , the third is palm oil certified - which means they use ethically sourced oil , the fourth is for companies or products which used a mixed supply of certified and uncertified oil , and the final is a fail . A fail means the company have refused to provide details when approached by POI , or that they use uncertified palm oil . 'It is going to make big waves , ' Lorinda said , speaking of the app . ' I don ’ t know what this person or company thinks they ’ re going to achieve . It 's not the correct way to approach us ' . 'Whoever it is is worried… in a way that ’ s a good thing because it shows the app is going to do exactly what it ’ s meant to , ' she continued . In recent years there has been controversy over illegal deforestation in south-east Asia . Animals such as orangutans , tigers and elephants are losing their natural habitats to the deforestation . As a single mother to her young daughter , the POI founder said the letter was frightening , and it was now being investigated by detectives . And she had a message for the anonymous sender : 'If they ’ re worried , why not send us a letter and say how are our brands sitting in that app … instead of sending something like that ' . A controversial ingredient in recent years , palm oil is used in a large amount of products found on supermarket shelves , from foods to beauty and cleaning products . The issue surrounding the resource stems from the illegal deforestation of areas in Borneo and Sumatra , which is having a devastating impact on the animals that call these areas home . Orangutans , tigers , rhinoceroses and elephants are among the native animals which face extinction as more and more land is cleared to harvest the cheap oil . Harvesting the crops from which the oil comes from is not the issue at the centre of the debate , rather the uncertified and dangerous ways the resource is being collected and sold .
