However, if you modify them (fix bad translations), etc. I don't think you should necessarily dump them.

Also, the intent of the TOS is to "Do No Harm" to Google, Google's customers, and The World. If you are keeping a cache longer than 15 days and are not doing any harm, then I don't think your are violating the spirit of the TOS.

For example, if you are running Google Adsense and your translations are generating a lot of traffic for Google, and good revenue for Google, I don't think Google will be unhappy with you, but of course they cannot publish such a policy.

On the other hand, if you are caching translations and using them to drive traffic to Google's big competition, then Google might care.

So, if you want to be on the safe side, just drop all translations in the database that are older than 15 days, and you will be in compliance with the most strict interpretation of the TOS.

Don't Worry. Be Happy. Do No Harm.

That's why default value of cache time to live is 15. Every night mod automatically removes old cache. Everybody is happy
