There's some tension between wanting to be taken seriously ("we" makes it sound like there is a team supporting the product) and using the correct pronoun number for a single author. I see the appeal of using the royal "we" everywhere, even when there is only one person behind the project, because at least then the pronouns don't need to be updated once a second team member joins.
Is it better to us "I" or "We" when running a site yourself? And does the answer change depending on the type of site?
Even if you're the sole author of the app/site, the voice of any text should be abstracted away from your identity at least to this small degree. Use "I" only in testimonials, quotes, or in a "message from our founder".
This discipline helps keeps the voice/tone of the text consistent throughout the app, which inspires trust and confidence. It's more polished and professional, especially if you ever contemplate expanding your team.
So it comes down to how much you want your site associated with you personally, versus having its own identity (and associated "team", even if it's just you on the team).
For hobby projects, I generally go with 'I'; for anything I'm asking for money in exchange for a service, I go with 'we'.
If you feel uncomfortable using 'we' instead of 'I', just file a C-corp and get a registered agent. Now there's two of you, and when you're speaking as the corporation, it's a 'we'. (I'd argue it's always a 'we' for the C-corp, though, because again, it's a team, and teams are always plural.)
Of course, I've been known to use language strangely, so make up your own style rules and go with them.
Pretigious Technologies takes privacy seriously.
Sounds professional and is "future proof."
I agree, either "I" or a proactive statement of intent: "We guarantee your data is deleted" or along similar lines ...
I would use "I" as long as it is correct.
Gooogle takes your privacy seriously.
"I, Sergei, takes you privacy seriously." Not as convincing.
- you have to open a new tab.
- then remember the name of the stuff and type it.
- then make sure you are online (not in a plane).
- then type it without all the LO tools such as good spell check and typography fixes.
- then you wait for the generation, download the file and the go to the download directory, and then copy it where you want.
All in all, I'd say it's the same, except you can change stuff in the LO version, work offline, and refer to the one tool that does all the other stuff as well instead of having to manage 1000 of tools to tools such a simple task.
Like Microsoft signing data protection agreements with the European Union, before any serious company would consider using their cloud type legal documentation.
Feedback:
Consider replacing "We take privacy seriously" with "I take privacy seriously".
Better yet, consider removing that sentence so you don't make people second guess it. It's even easier then because there's less information that needs mental processing. You might just say, "Once you generate your memo, your information is deleted forever" or you might not say anything at all.
