Hello,

1. The fact is that the spy software was installed in your mobile by your mother and not the company that developed the software. If you need to sue someone, it is the person who installed the spyware in your mobile.
2. As you are still a minor and most likely dependent on your parents, certain amount of parental restrictions and controls might lie as a societal norm and the breach of privacy will not kick in to take any legal action.
3. The software company would have obtained requisite sanctions before rolling out the product in the market and if someone purchases the product and uses it, it is wholly the discretion of the buyer/user.It would be best that you sort things out with your mom. 

1.  The Software Co. did not install any "spy software" on your Mobile /Computer. Hence they cannot be prosecuted for any offence.

2. You Mom installed the  "spy software" on your Mobile /Computer, hence your Mom can be prosecuted for Criminal Intimidation, Nuisance, Breach of Trust, etc....

3. However, since you are a Minor (16 years), and your Mom is your biological & natural Guardian, you cannot prosecute anybody as a minor. 

No, you cannot .

No you can't because spy software needs to download from play store or in pre installed in your mobile or its need to download from internet, If its pre installed than kindly check company terms and conditions and disclaimer.

- No , the said mobile company is not accountable for the said Act, because it is your mother who has taken services from the said company. 

- However, being the minor , you can inform the said company only. 

Dear Client,

You may make a complaint to the nearest police station against your mother.

You cannot file any such case against the company especially for the acts done by your mother against you.

not maintainable against company. 

Hello!

1.You are a minor, and you cannot institute a civil suit or writ petition without a legal guardian. 

2. The software is installed in your phone by your mom. The company will evade it's liability by stating that you have voluntarily installed it after knowing the consequences.

3. A criminal complaint can be lodged against them under IT Act if they have stored/transferred some extremely sensitive data like nude photographs to someone else. 

4. The exact remedy will differ depending upon the kind of privacy breach. 

Dear Sir/Madam,

You are suggested to file the police complaint against that company as well as against your mother for breach of privacy. 

No you cannot file case against a software company because your mother installed the software in your phone. 

The spy company is not responsible as your mom has installed it in your phone.
