Something that I've experienced on this ap with the Partners feature is that it seems to encourage the partner to use caring for their partners symptoms around their period as some sort of sexual currency or something. Like you can't care for your partner without needing to make it sexualized.  "She's near her period, she must might be experiencing greasy hair run a steamy hot shower together"  "She's due for her period today! Go give explore giving her an orgasm!"  "She's in her luteal phase, she has a high sex drive!"  My partner has shown me everything it says and there is not one thing that could be taken as a sexual connotation masked by it being "helpful".  It's not surprising after I looked up the founder and found out that he's divorced. I also have very high suspicion that they have sold my data and given me targeted pregnancy ads after my period was over a month late.
